+	Use only detect_input_pending to check for pending kbd input.
+	(That `select' saw something on channel 0 doesn't mean it is
+	kbd input; it could be an expose event.)
+
+	* keyboard.c (read_avail_input) [FIONREAD]:  Now static.
+	New arg specifies value of NREAD;
+	if it is nonzero, don't call get_input_pending to get it.

+
+	* Makefile: Set $(MAKE), since some Make versions don't have it.

+
+	* process.c (create_process): Don't bother calling set_exclusive_use

+
+	* x11term.c, x11fns.c, x11term.h: New files from rfrench@athena.mit.edu
+	In x11term.c, the function `read_events_block' has been `if 0'd

+	This was formerly done only on HPUX, and worked there.

+
+	* process.c (wait_reading_process_output): Change the test on
+	read_kbd to avoid losing on 80386 Xenix.

+1988-01-29  Richard Stallman  (rms at frosted-flakes.ai.mit.edu)

+	Change first arg (0) to getcwd to (char *) 0
+	Also, call `free' on value returned (after we save it)

+1987-03-22  Richard M. Stallman  (rms at prep)
+

+	length of NAME, not STRING.
+
+	* emacs.c (main) [VMS]: If SHAREABLE_LIB_BUG, declare `environ'
+	noshare and initialize it from `envp'.
+
+1987-03-20  Chris Hanson  (cph at prep)
+
+	* process.c (pty): On hp-ux, do not enable TIOCREMOTE.  See the
+	code for a comment explaining why.

+
+	* bytecode.c (Fbytecode):
+	Another SWITCH_ENUM_BUG problem.
+
+	* sysdep.c: If not HAVE_TERMIO, override any definition of TCSETAW.
+	Ultrix 2.0 has a TCSETAW but it requires a struct termio.
+	Since HAVE_TERMIO is not set, sysdep uses struct sgttyb,
+	and the real TCSETAW does not work with this.
+
+	* sysdep.c (getwd): Discard everything before first slash.
+
+	* termcap.c (tgetent): Delete VMS code to delete / from filename.

+	files to link into temacs.
+
+1987-03-12  Richard M. Stallman  (rms at prep)
+
+	* fileio.c (Fsysnetunam): Make this function conditional on
+	HPUX_NET, not on HPUX.

+	Alternative names for struct symentry and struct auxentry.
+

+	HPUX: Set baud-rate to 9600 (not 38400)
+	For some reason the former is reported to work faster(!?)
+
+1987-03-10  Richard M. Stallman  (rms at prep)
+
+	* dispnew.c (init_display): Declare alternate_display only if X.
+
+1987-03-09  Richard M. Stallman  (rms at prep)
+
+	* m-alliant.h, crt0.c for alliant:
+	Must save _curbrk when dumping (from ADJUST_EXEC_HEADER)
+	and restore it in crt0, because _curbrk itself isn't dumped.

+	No code is shared with normal unexec.
+
+1987-03-08  Richard M. Stallman  (rms at prep)
+

+
+1987-03-07  Richard M. Stallman  (rms at prep)
+
+	* lisp.h: #ifndef the definitions of XUINT, XSET, XMARKBIT, etc.

+	* ymakefile (LIBX): add -lXMenu.
+
+1987-03-03  Richard M. Stallman  (rms at prep)
+
+	* fileio.c (Fwrite_region): Really put the `fstat' after
+	the `fsync', trying to solve spurious "file has changed" warnings.
+	This reverses a change made on Jan 28 which was described then
+	as putting the `fstat' after the `fsync' but which in fact
+	was exactly the opposite.  The truth is that anciently the
+	`fstat' was after, and on Jan 28 it was moved before.
+	The change on Jan 28 was to fix some sort of RFS problem.
+	I don't know whether the change itself or just its description
+	was incorrect.
+
+	* Version 18.38 released.
+
+1987-02-28  Chris Hanson  (cph at prep)
+
+	* fileio.c: Added `sysnetunam' function for controlling remote
+	file access connections under hp-ux.

+	* s-hpux (LIBS_SYSTEM): Added `-ln' which is used by `sysnetunam'.
+
+1987-02-28  Richard M. Stallman  (rms at prep)
+
+	* xdisp.c (display_text_line): Typo in line that fixes tab_width.
+
+1987-02-27  Richard M. Stallman  (rms at prep)
+
+	* dispnew.c (Fopen_termscript): `report_file_error'
+	requires list as 2nd arg.
+
+1987-02-26  Richard M. Stallman  (rms at prep)
+
+	* xmenu.c: New file defining Fx_popup_menu.
+	* emacs.c (main): Call syms_of_xmenu.
+
+	* buffer.c (Fother_buffer): Condition for assigning to
+	`notsogood' was backwards (should be if null).
+
+1987-02-23  Richard M. Stallman  (rms at prep)
+
+	* keymap.c (access_keymap): No longer check lower case
+	equivalent of an upper case letter that is undefined.
+
+	* keyboard.c (read_key_sequence): If an upper case letter
+	is undefined, and corresponding lower case letter is defined,
+	use the lower case letter instead.
+
+	* emacs.c: Delete all ALLIANT conditionals that used to
+	save and restore _curbrk.  Special code in crt0.c now
+	handles this.
+
+	* crt0.c [ISI68K]: Assembler code to put a .word 0 after _start.
+	Include the dummy arg `ignore' in start1.
+
+	* crt0.c [orion/pyramid/celerity]: ALLIANT now uses this case,

+
+	* m-alliant2.h: File deleted.  Use m-alliant.h for version 2.
+	* m-alliant1.h: Don't look for ALLIANT2 to be defined.
+	Now ALLIANT1 is defined for version 1 and not for version 2.
+	Define NO_ARG_ARRAY only for version 1.
+	Define START_FILES so GNU crt0.c gets used.
+	Remove definition of TEXT_START (safe since GNU crt0.c is used).
+	Add to ADJUST_EXEC_HEADER something to set unexec_text_start.
+
+1987-02-22  Richard M. Stallman  (rms at prep)
+
+	* dispnew.c (Fopen_termscript):  Close existing termscript
+	file before trying to open a new one.  Report open failure
+	with report_file_error.
+
+1987-02-21  Paul Rubin  (phr at prep)
+
+	* window.c (set-window-buffer): typo "set-widow-buffer".
+
+1987-02-19  Richard Mlynarik  (mly at prep)
+
+	* lisp.h:
+	Add type Lisp_Window_Configuration, delete Lisp_Temp_Vector.

+
+	* window.c (F{set,current}_window_configuration):
+	New lisp-callable functions which do the guts of
+	Fsave_window_excursion.
+
+	Also fixed a bug in which point was not being restored in
+	buffer currrent at end of save-window-excursion and that buffer
+	was not current when the config was recorded (It is supposed
+	to not be restored if it was current at the start)
+
+	* alloc.c (mark_object):
+	Add case for Lisp_Window_Configuration; remove code for
+	Lisp_Temp_vector.
+
+	* window.c, window.h:
+	Rename Fshow_buffer Fset_window_buffer (which was previously the
+	synonym in subr.el)
+
+	* keyboard.c, minibuf.c: Window configuration caller changes.
+
+	* print.c (print):
+	Understand Lisp_Window_Configuration's.
+	Print a disturbing message if encounter an illegal dtp --
+	perhaps this should core-dump?
+
+1987-02-17  Richard Mlynarik  (mly at prep)
+
+	* dired.c (Ffile_attributes):
+	Use make_number.  (XINT doesn't work on LHS of assignment)
+
+1987-02-17  Richard M. Stallman  (rms at prep)
+
+	* doc.c (get_doc_string, Fsnarf_documentation):
+	In vms4.4, avoid system bug by using sys_translate_unix
+	to translate filename to VMS format before opening.
+
+1987-02-16  Richard M. Stallman  (rms at prep)
+
+	* crt0.c: Don't define `environ' if DONT_NEED_ENVIRON is defined.

+
+1987-02-13  Richard M. Stallman  (rms at prep)
+
+	* process.c: TCP connection feature from markl@jhereg.lcs.mit.edu.
+	Uses a process-object to represent a connection.
+	childp field is now Qt for a real subprocess,
+	or a hostname string for a tcp connection.
+	NETCONN_P checks this.
+	Status strings "open" and "closed" replace "run" and "exit"
+	for tcp connections only.  New function Fopen_network_stream.
+
+	* dired.c (Ffile_attributes): Use XINT to store the inode #.
+	It can be out of range for integers.
+
+1987-02-12  Richard M. Stallman  (rms at prep)
+
+	* xdisp.c (try_window): Fix paren errer in checking hpos
+	against hscroll.  This caused window_end_pos to be wrong
+	when there was hscroll.
+
+	* xdisp.c (display_text_line): Move code that inserts `$'
+	at bol for hscroll, so that its alteration of p1 does not
+	interfere with setting point_hpos.
+	Use lastpos instead of pos in that code.
+	Make lastpos be accurate in all cases including when there
+	is truncation.
+
+	* xdisp.c (display_string): mincol==-1 means no minimum.
+	* xdisp.c (display_text_line): Use -1 for mincol of minibuf promp.
+
+1987-02-11  Richard M. Stallman  (rms at prep)

+
+	* tparam.c (tparam): Supply code for NO_ARG_ARRAY case.

+	Vminibuf_scroll_window.  Make it a Lisp variable.
+	* window.c (Fscroll_other_window): Validate
+	Vminibuf_scroll_window since user could store a non-window there.
+
+	* window.c (temp_output_buffer_show):
+	Call Vtemp_output_buffer_show_hook to do the work, if not nil.
+
+	* window.c (Fminibuffer_window): New function.
+
+	* print.c (print, syms_of_print): If print_escape_newlines
+	is nonzero, print newlines in strings as \n.
+
+	* minibuf.c (read_minibuf): Reduce arg to get_minibuf by 1.
+	Thus, use *Minibuf-0* for outer-level minibuffers.
+
+	* keyboard.c (command_loop_1): Pass 2nd arg to Fsit_for.
+	* minibuf.c (temp_minibuf_message): Likewise.
+
+	* dispnew.c (Fsit_for): 2nd arg non-nil means don't redisplay.
+
+	* s-vms.h: Don't define VMS4_0, VMS4_2 or VMS4_4.
+	* s-vms4-[024].h: New files that include s-vms.h and also
+	define VMS4_0 or VMS4_2 or VMS4_4.
+
+	* vmspaths.h: Remove `/emacs' from all paths, to go with a change
+	in emacs.com that includes that path segment in emacs_library.
+
+	* term.c (term_init): Different message on VMS for invalid termtype.
+
+	* alloc.c (Fgarbage_collect): After GC, clear marks
+	in the dummy buffers buffer_defaults and buffer_local_symbols.
+
+1987-02-07  Richard M. Stallman  (rms at prep)
+
+	* window.c (Fnext_window): Restore old meaning of t as 2nd arg:
+	count minibuffer window even if not active.
+	Non-t-non-nil as 2nd arg means never count minibuffer window.
+
+	* window.c (window_loop): Rewrite to work the old way.
+	The new way did not work when deleting windows.
+
+1987-02-05  Richard M. Stallman  (rms at prep)
+
+	* m-sequent.h: Undef old definition of KERNEL_FILE so no warning.
+
+	* process.c (read_process_output): Don't restore selected buffer
+	after filter; sometimes setting buffer is useful in filter functions.
+
+
+1987-02-02  Richard M. Stallman  (rms at prep)
+
+	* keyboard.c (kbd-buffer_store_char): Fix paren error.
+
+1987-01-31  Richard M. Stallman  (rms at prep)
+
+	* window.c (window_loop): Rewrite not to pass t as 2nd arg
+	to Fnext_window by starting loop from the window after
+	the minibuffer.  This was sole use of the feature.
+
+	* window.c (Fnext_window): Change meaning of t as 2nd arg.
+	It now means to ignore the minibuffer even if it's active.
+
+1987-01-29  Richard M. Stallman  (rms at prep)
+
+	* cmds.c (Fforward_line): Correct the returned value.
+

+
+	* keyboard.c (kbd_buffer_store_char):
+	Ignore meta bit while checking for C-g, if meta-flag is clear.
+
+	* unexec.c (make_hdr): typo `bas_start'.
+
+	* sysdep.c: Declare errno explicitly since errno.h may fail to.
+
+	* fileio.c (Fwrite_region): Move the fstat after the fsync.
+	[Note: the above sentence was incorrect; actually the fstat
+	had been after and was moved *before* the fsync. -- RMS, Mar 3.]
+	Avoids RFS lossage with fsync (maybe).
+
+	* s-rtu.h: Define NLIST_STRUCT and LDAV_SYMBOL.
+	* m-masscomp.h: Check machine type to choose between C_ALLOCA
+	and HAVE_ALLOCA.

+
+	* fileio.c (Fsubstitute_in_file_name):

+
+	* sysdep.c (select): If no subprocesses, make `child_changed'
+	local and initialized to 0.
+
+	* xdisp.c (display_string): If TRUNCATE is 0, display all the
+	way to window edge; don't stop one column short.
+
+1987-01-24  Richard M. Stallman  (rms at prep)
+
+	* unexec.c (make_hdr): New var `bss_end' holds end-of-bss address.
+	This simplifies computation of bss size while keeping it from
+	being negative.
+
+1987-01-23  Richard Mlynarik  (mly at prep)
+
+	* fileio.c (Fexpand_file_name):
+	Have to do checks for "//" "/~" etc even if filename is
+	non-absolute, otherwise things like "~user1/~user2" aren't
+	expanded correctly (was getting "/u/user1/~user2" instead of
+	"/u/user2")
+
+	* doc.c (Fsubstitute_command_keys): Doc fix.
+
+	* m-stride.h: Fixes from bruce@stride.com
+
+1987-01-22  Richard M. Stallman  (rms at prep)
+
+	* eval.c (Feval, apply_lambda): When protecting a vector
+	of evaluated arguments, across the loop that evals them,
+	always set gcproN.nvars to the number of args

+	bf_cur->directory.
+

+
+1987-01-08  Richard M. Stallman  (rms at prep)
+
+	* search.c (Freplace_match): Change declaration `char' to `int'.
+	Declaring a scalar variable `char' is nearly always wrong

+	and that caused crash in GC).
+
+	* window.c (all functions): Add register declarations.
+
+	* window.c (Fsave_window_excursion):

+
+	* xdisp.c: Changed all uses of window_end_pos to use
+	window_end_valid appropriately as well.
+
+	* process.c (wait_reading_process_input):

+
+	* keyboard.c (Fsuspend_emacs):
+	If `suspend-emacs-hook' returns t don't suspend
+	-- assume the hook did the equivalent of `suspending' for us
+	(including calling suspend-resume-hook if necessary.)

+	on screen of point.
+
+	Make this_line_* static variables.
+	
+	In DoDsp, rearrange the tests to see whether to use cached
+	line info to be a little faster.
+	Fix some bugs in which cursX and cursY might not be updated
+	correctly when using cached info (needed to add this_line_hpos
+	variable to do this correctly)
+	(Added unnecessary gotos and  label `cancel' for added readability)
+
+	* fns.c (Fy_or_n_p):
+	Move cursor to start of line after reading answer so
+	user knows emacs is proceeding.  (Like after minibuffer exits)
+
+	* dispnew.c (Fopen_termscript):
+	Arg of nil means to close current termscript file (if any)
+
+	* keymap.c (Fwhere_is_internal):
+	Doc fix.

+	start of the echo area, but not have any echo appear until one
+	second later.
+
+1986-12-17  Richard M. Stallman  (rms at prep)
+
+	* editfns.c: Add register declarations and a few vars for cses.
+	* editfns.c (Fchar_equal): Avoid indexing downcase_table
+	with numbers larger than 0xff.
+
+1986-12-16  Richard M. Stallman  (rms at prep)
+
+	* alloc.c: New garbage collection technique for strings.
+
+	Strings that have string blocks individually allocated
+	are called "large strings".  Other strings are called "small".
+
+	The string blocks for small strings are now chained both ways and
+	there is a pointer to the oldest one of them in `first_string_block'.
+	The string blocks for large strings are chained only from the
+	latest to the oldest, and the latest is in `large_string_blocks'.
+
+	Garbage collection starts by setting MARKBIT in the `size' of
+	each large string.  This allows mark_object to distinguish them.
+	MARKBIT in string sizes is cleared by gc_sweep.
+
+	Large strings are freed individually by GC, like vectors.
+	Those in use are marked with ARRAY_MARK_FLAG in the `size' field.
+
+	Small strings are relocated, compressing them within their
+	string blocks.  
+	mark_object puts all slots that point at a string onto a chain
+	which runs from the string's `size' field, through all the slots
+	that used to point at the string.  The end of the chain is shown
+	by a number that is small enough to be a small string's length.
+
+	This new technique avoids calling malloc during GC.  Thus, there
+	is no danger of fatal error on exhausting memory.  Also, space
+	needed for strings is cut in half.
+
+	The new technique introduces a potential for bugs, however.
+	If any slot is marked twice--for example, if it is GCPRO'd
+	twice by different functions--and it contains a string,
+	the ref chain of the string may become garbled.  Sometimes
+	it will still work!  This is because a slot that's part of a
+	string's ref chain will look like a Lisp_Int if the next thing
+	in the chain is malloc'd memory.  But this will not win if the
+	next thing in the chain is a stack slot, or if malloc'd data
+	lives high up in memory.
+
+	To avoid this problem, MARKBIT is used in stack slots
+	to prevent double marking.
+
+	* bytecode.c (Fbytecode): Adjustment of gcpro1.nvars before
+	call to Ffuncall was off by one.
+
+	* alloc.c (make_uninit_string): make_zero_string renamed as this
+	and no longer zeros the contents.
+	* alloc.c (Fmake_string): initialize string contents.
+
+	* alloc.c (struct string_block): Now chained both ways thru
+	`next' and `prev' fields.  `first_string_block' exists.
+	Strings with individual string blocks are now called "large"
+	and these string blocks go in a separate chain which starts
+	from `large_string_blocks' and runs via `prev' fields only.
+
+	* alloc.c: Stop using clear_marks.  Make gc_sweep clear
+	the marks on all live objects.
+	
+	* alloc.c (malloc_warning, Fgarbage_collect): Eliminate mechanism
+	that defers malloc warnings during GC, since GC no longer calls
+	malloc.
+
+	* fns.c: Fding requires an arg; pass Qnil.
+
+	* m-alliant.h: define TEXT_START as 0x1000.
+	Don't define LIBS_STANDARD; the default (sharable) library
+	is said to work now.
+
+	* alloc.c (mark_object): Now pass address of slot being marked.
+	mark_object itself can alter the slot when necessary.
+	It now returns no value.  All callers changed to pass the address.
+
+	mark_object can now ignore the mark bit if it's set in the slot.
+	Callers need no longer make a copy in which mark bit is clear.
+	mark_object can clear the mark bit so these callers must still
+	set the mark bit again after calling mark_object on such slots.
+
+1986-12-15  Richard M. Stallman  (rms at prep)
+
+	* process.c (create_process): TIOCNOTTY needs no 3rd arg after all.
+	* sysdep.c (set_exclusive_use): ditto for FIOCLEX.
+
+	* emacs.c (Fdump_emacs): [ALLIANT]
+	Copy _curbrk into save_curbrk, not vice versa.
+
+1986-12-13  Richard M. Stallman  (rms at prep)
+
+	* sysdep.c (flush_pending_output): 3rd arg to TIOCFLUSH

+1986-12-11  Richard Mlynarik  (mly at prep)
+
+	* emacs.c,  dispnew.c:
+	Rename inhibit_x_windows inhibit_window_system.

+	code easier to accommodate.
+
+	* editfns.c (Fformat):
+	Move the increment of the number of args the format string wants.

+
+1986-12-05  Richard M. Stallman  (rms at prep)
+
+	* process.c (read_process_output): Read only one buffer worth
+	and return without trying to read more.  It used to loop
+	until all output was gobbled.  Now some callers do this loop
+	but not all of them.
+
+	* process.c (change_msgs): Call read_process_output repeatedly
+	until it returns 0 (no chars were read).
+
+	* term.c (write_chars): loop counting repeated chars leaves

+	as local map when calling Fwhere_is_internal.
+
+	* keymap.c (Fwhere_is_internal, where_is_in_buffer):
+	Combine the two functions.  This adds two arguments to
+	Fwhere_is_internal: KEYMAP and FIRSTONLY.
+	To get the old behavior, KEYMAP must be (current-local-map).
+	Therefore, KEYMAP is a mandatory operand for Lisp callers.
+
+	* keymap.c (Fwhere_is): Pass new args to Fwhere_is_internal.

+	convert args from Lisp_Object to int or char *, defaulting
+	any not specified.
+
+	Don't GCPRO; should not be needed since eval is not called.
+
+	* editfns.c (format1): Args are ints or char *'s,

+	Don't core-dump if data in obarray is invalid
+
+1986-12-01  Richard M. Stallman  (rms at prep)
+
+	* m-att3b.h: on 3b2, 3b5 and 3b15, #define C_OPTIMIZE_SWITCH null
+	since -O triggers compiler bug affecting push_key_description.
+
+1986-11-28  Richard Mlynarik  (mly at prep)
+
+	* keyboard.c (read_key_sequence):
+	Delay setting up the local vars pointing to keymaps until a
+	character has been read.  This is in order that a change of keymap
+	`behind our back' (eg due to a subprocesses action) will be seen.
+
+	* xterm.c:
+	Typo.
+

+	Use those macros.  Create an enum type for the flags
+	and change the flag names to avoid conflict with the macros.

+
+	* keyboard.c (Frecursive_edit): If not the top-level edit,
+	specbind standard-output and standard-input to t.
+	* keyboard.c (command_loop_1): Don't set those two vars.
+	This avoids clobbering them permanently when minibuffer is used.
+
+1986-11-25  Richard M. Stallman  (rms at prep)
+
+	* callproc.c (child_setup): New arg `envlen' is length
+	of the list Vprocess_extra_environment.
+	This list's elements (strings) are put at the front of
+	the environment for the other program.
+
+	* callproc.c (Fcall_process): Some rearrangement of

+	* keyboard.c (command_loop_1): Notice the returned values.
+
+	* window.c (change_window_height):
+	Add new variable delta1 so no need to use delta
+	for two different things.
+	Making window bigger to equal its parent's size used to crash.
+	Fix it by different way of computing delta1 in that case.
+	Move some variable decls to inner blocks and add "register".
+
+1986-11-24  Richard M. Stallman  (rms at prep)
+
+	* buffer.h: `modtime' field = 0 now means no info on visited file.
+	Nonexistent visited file now represented by -1.
+
+	* fileio.c (Fverify_visited_file_modtime):
+	Adjust for changed meaning of `modtime'.
+
+	* fileio.c (Finsert_file_contents):
+	If visiting and file doesn't exist, finish visiting (updating
+	various buffer slots) before getting error, and set modtime to -1.
+
+	* bytecode.c (Fbytecode): Rarrange all the Bvarref cases to
+	share most of the code.  Likewise for Bvarset, Bvarbind
+	and Bunbind cases.  Makes it smaller and makes all
+	Bvarrefs use the fast inline code.
+
+	* keymap.c (Fdefine_key, Flookup_key):
+	Regard chars 0200 and up as equivalent to 2 char sequences
+	starting with meta_prefix_char.
+
+	* search.c (search_buffer and callers):
+	Complete rewrite from king@kestrel using simplified Boyer-Moore
+	algorithm.  Meaning of returned value changed.
+	* search.c (bcmp_buffer_translated): No longer used; deleted.
+
+	* search.c (ScanBf, scan_buffer): complete rewrite of ScanBf
+	and nearly all is now in scan_buffer, a new function.
+	* cmds.c (Fforward_line): Complete rewrite; now calls scan_buffer.
+
+	* search.c (Fscan_buffer): Delete this.
+	* bytecode.c (Fbytecode): Just get error if Bscan_buffer is used.
+
+	* ymakefile: Rename TEXT_START_ADDR to LD_TEXT_START_ADDR
+	to avoid shortname trouble (ymakefile is processed thru
+	the system's cpp).
+
+	* sysdep.c (init_sys_modes): Change #ifdef USG to #ifdef _IOFBF
+	around the call to setvbuf.
+
+	* sysdep.c (bcopy): declare it to return int
+	so that a forward declaration is not needed
+	so there is no problem defining it as a macro.
+
+	* fileio.c (Fwrite_region): Don't try fsync on 4.1bsd.
+
+1986-11-23  Richard M. Stallman  (rms at prep)
+
+	* eval.c (record_unwind_protect, specbind, unbind_to, Funbind_protect):
+	struct specbind now has a new slot `func'.  An internal
+	unwind-protect stores the C function address there; else it's 0.
+	Lisp_Internal_Function data type no longer used.
+	Result is no more dependency on where in the address space
+	function addresses are found.
+
+	* xterm.c (x_term_init): Better message if server does not
+	respond.
+
+	* version 18.31 released.
+
+	* xterm.c, xfns.c (Vxterm1): Lisp var `xterm' now points at
+	Vxterm1, which is initialized like Vxterm but never examined.
+
+	* xterm.c (XTread_socket): Use C-x C-@ to indicate mouse click.

+	before dumping and restore when starting dumped Emacs.
+
+	* process.c (wait_reading_process_input):
+	[ALLIANT] if select returns with EFAULT, just set Available = 0.
+	[always] copy errno right after the select and check the copy
+	in case another system call could alter it in between.
+
+	* m-alliant.h, m-mg1.h: New machines supported.
+
+	* ymakefile: Make START_FILES a preprocesser variable
+	and don't change it if already defined.
+	* m-gould.h: Move special gould value of START_FILES here.
+
+	* fileio.c (syms_of_fileio): Define variable vms-stmlf-recfm.
+	* sysdep.c (sys_creat): If vms_stmlf_recfm is nonzero,

+
+	* eval.c (unbind_catch): Don't ref thru handlerlist if null.

+	method of suspending with ptrace.
+
+1986-11-19  Richard M. Stallman  (rms at prep)
+
+	* xterm.c (x_term_init): Delete attempt to set up
+	a handler for SIGIO.  This was normally overridden in
+	init_keyboard so it didn't matter; but this handler
+	is invalid, so it crashed if it ever did get called.
+
+	* indent.c (compute_motion): Fix screwy #if celerity || ATT3B
+	which is invalid.
+
+1986-11-18  Richard M. Stallman  (rms at prep)
+
+	* keyboard.c (command_loop_1):
+	Must check to reselect buffer and flush minibuf message
+	before trying fast_read_single_key.  Else have lossage
+	typing printing chars when minibuf message is displayed.
+
+	* keyboard.c (Fsuspend_emacs):
+	Execute suspend-resume-hook value on resumption.
+
+	* lisp.h: Make initialized global.
+	* data.c (init_data): Undo last change; not needed now.
+
+1986-11-18  Richard Mlynarik  (mly at prep)
+
+	* emacs.c (main):
+	Giving `inhibit_x_windows' an initialisation loses;
+	do it explicitly.
+
+	* xfns.c (Fx_rubber_band):
+	Make interactive.
+
+1986-11-18  Richard M. Stallman  (rms at prep)
+
+	* dispnew.c (window_change_signal):
+	New function to handle SIGWINCH, defined only if SIGWINCH is.
+	Turned on in init_display if CANNOT_DUMP or if initialized.
+
+	* data.c (init_data), editfns.c (init_editfns):
+	Test initialized, not Vpurify_flag.  Use explicit
+	conditionals to avoid the test when CANNOT_DUMP.
+
+1986-11-17  Richard M. Stallman  (rms at prep)
+
+	* buffer.c (Ferase_buffer): Zero the buffer's save_length.
+	Future text after erase is unrelated to past text
+	so should not suspend auto saving if future text is smaller.
+
+	* buffer.c (init_buffer_once):
+	Was passing entire structure to bzero; now pass address.
+
+	* fns.c: Prevent warning in 4.3 where param.h does #define BSD
+
+1986-11-16  Richard M. Stallman  (rms at prep)
+
+	* dispnew.c (init_display): Set window-system to symbol x, not "X".

+
+	* xfns.c (grey_p): Insert missing commas.
+	* emacs.c (main): Fix typo "ihhibit_x_windows".
+
+	* xterm.c (x_term_init): Delay calling XPopUpWindow
+	till after Vxterm is set.  Also must include lisp.h.
+	Also always set Vxterm if CANNOT_DUMP.
+
+	* xfns.c, xterm.c: Include signal.h before xterm.h
+	because on 4.3 both of them define sigmask
+	and only xterm.h considers the case that it is already defined.
+
+	* buffer.h: Add BufferSafeCeiling and BufferSafeFloor.
+
+	* process.c (Fprocess_send_eof):
+	Now has conditional on DID_REMOTE, which is defined
+	if TIOCREMOTE is actually used.
+
+1986-11-15  Richard M. Stallman  (rms at prep)
+
+	* Emacs version 18.30 *
+
+	* xdisp.c (display_string):
+	Change minwidth and maxwidth args to mincol and maxcol:
+	minimum and maximum absolute hpos to end at.
+	Change all callers (all in xdisp).
+
+	* xdisp.c (display_mode_element)
+	Similar change of minwidth and maxwidth args.
+	This permits considerable internal simplification
+	and deletion of the function display_mode_element_1.
+
+	* xdisp.c (decode_mode_spec): Flush unused arg minwidth.
+	Change call (in display_mode_element).
+
+1986-11-14  Richard M. Stallman  (rms at prep)
+
+	* process.c (create_process): Don't get a pty
+	if the new variable Vprocess_connection_type is not t.
+	This is the Lisp variable process-connection-type.
+
+1986-11-13  Richard M. Stallman  (rms at prep)
+
+	* crt0.c: Rename GLOBAL_START_{DOT,NO_DOT}
+	to {DOT,NODOT}_GLOBAL_START to avoid shortnames trouble.
+	* m-vax.h, m-tahoe.h, m-sequent.h: same change.
+
+	* m-att3b.h: Turn off #define VIRT_ADDR_VARIES
+	(kk says no need for it).
+
+	* keyboard.c (Fcommand_execute):
+	Zero debug_on_next_call before running the command.
+
+1986-11-12  Richard Mlynarik  (mly at prep)
+
+	* data.c (Fsequencep):
+	(sequencep nil) => t
+
+	* xdisp.c (display_string):
+	Put a "|" at end of mode-lines of partial-width windows.
+
+	* xdisp.c (various):
+	mode-line-format %259 means to pad field to 259, but not to
+	truncate it.
+	(259 . <format>) also means to pad.
+	(-259 . <format>) means to truncate to 259, but not to pad.
+	[So (-259 . (259 . x)) means to format x -exactly- 259 chars wide.]
+
+	* dispnew.c (Fding):
+	Do not terminate macro-definition if given an argument
+	(This is so things like asynchronous process notifications
+	can beep but not screw)
+
+1986-11-10  Richard M. Stallman  (rms at prep)
+
+	* fileio.c (Fset_file_modes): [APOLLO] must reset
+	modtime after changing the modes.
+
+1986-11-10  Richard Mlynarik  (mly at prep)
+
+	* buffer.c (init_buffer_once):
+	There is no lisp variable corresponding to buffer-name
+
+1986-11-10  Richard M. Stallman  (rms at prep)
+
+	* xdisp.c (display_string): Measure new line length
+	from start of line body.
+
+1986-11-09  Richard M. Stallman  (rms at prep)
+
+	* lread.c (oblookup, map_obarray):
+	Do not use XFASTINT on `next' fields of symbols.
+	Fix incorrect sense of test for end of bucket.
+
+	* filelock.c (current_file_owner):
+	Fix incorrect sense of test with `kill'
+	for death of previous locker.
+
+	* keyboard.c (get_char):
+	Arg of -1 now means don't do redisplay.
+	Rearrange conditionals so detect_input_pending is not called
+	in certain cases.
+
+	* keyboard.c (read_key_sequence):
+	New arg nodisplay, nonzero means pass -1 to 1st call to get_char.
+
+	* keyboard.c (command_loop_1):
+	After a command that does direct screen updating,
+	if buffer_shared is not more than 1,
+	pass 1 for nodisplay to read_key_sequence.

+	value of MinibufDepth as a Lisp Int.
+
+	* dired.c (Ffile_attributes): Return inode # as element 10.
+
+	* dispnew.c (update_line):
+	Fix bug that noop'd the attempt to let new explicit spaces
+	match the implicit space past end of old line.
+	Also do not ignore trailing spaces in a highlighted line;
+	instead, give it more trailing spaces so it reaches the margin.
+
+1986-11-08  Richard M. Stallman  (rms at prep)
+
+	* data.c (init_data): Don't call signal if purifying.
+	* ymakefile: Stop using gould-sigvec.s.
+	No longer needed now that signal really isn't called.
+	* unexec.c: Eliminate gould-specific code to
+	reinitialize gould-sigvec.s.
+
+1986-11-07  Richard M. Stallman  (rms at prep)

+	* m-vax.h: Turn off NO_REMAP.
+
+	* sysdep.c (end_of_{data,text}): Omit them if CANNOT_DUMP.
+
+	* fileio.c (Fwrite_region): APOLLO is now like VMS
+	in doing the stat after the close.
+
+	* emacs.c (main): If APOLLO, don't call malloc_init.
+	We use the system's malloc on the Apollo.
+
+	* editfns.c (init_editfns):
+	If CANNOT_DUMP, do all the work, regardless of Vpurify_flag.
+
+	* alloc.c (mark_object): If not SWITCH_ENUM_BUG
+	don't cast the switch quantity to int.

+
+	* unexec.c (makehdr): Code to adjust, default and validate
+	data_start and bss_start now common to COFF and non-COFF cases.
+
+	* unexec.c (makehdr): Param SEGMENT_MASK controls rounding of
+	memory-address of text-data boundary (default is pagemask).
+	[COFF only] SECTION_ALIGNMENT controls rounding of file addresses
+	of section beginnings; default is no rounding.
+	[non-COFF] ADJUST_EXEC_HEADER is hook to be executed
+	before filling in a_text, etc. of the header.
+
+	With these parameters, all known machines can be handled
+	with no special conditionals.
+
+	* m-sun1.h, m-sun2.h, m-isi-ov.h: Define SEGMENT_MASK.
+	* m-stride.h, m-nu.h, s-umax.h: Define SECTION_ALIGNMENT.
+	* m-masscomp.h, m-gould.h, s-hpux.h: Define ADJUST_EXEC_HEADER.
+	* m-gould.h: Define A_TEXT_OFFSET = sizeof (hdr)
+
+	* unexec.c (makehdr): Remove ibmrt conditionals
+	that adjusted a_text or equivalent, by just copying from
+	the old file when NO_REMAP.
+
+	* unexec.c (makehdr): Zero supplied as entry_address
+	means copy it from the old file.
+	* emacs.c (Fdump_emacs): Pass 0 as entry_address to unexec.
+
+	* unexec.c (copy_text_and_data):
+	Two fixes for A_TEXT_OFFSET case:
+	Don't decrement `end', and remove (unconditionally)
+	the lseek before writing the data segment.
+
+1986-11-06  Richard M. Stallman  (rms at prep)
+
+	* keymap.c (apropos1): Use Fdocumentation_property, not Fget,

+
+1986-11-05  Richard M. Stallman  (rms at prep)
+
+	* alloc.c (Fcons, Fmake_symbol, Fmake_marker, gc_sweep):
+	The free-list pointers in symbols, conses and markers
+	are now C pointers cast as ints and stored in the XFASTINT.
+	This may make faster code and in any case avoids problems
+	with machines where access with XPNTR relocates the pointer.
+
+	* lread.c (oblookup, map_obarray):
+	Use XFASTINT when comparing a Lisp_Object against zero.
+
+	* minibuf.c (read_minibuf):
+	If noninteractive, print the prompt, since
+	it won't be displayed in the normal way.
+	In any case, pass Fread the string rather than a buffer
+	when reading an s-expression.
+
+	* auxdoc.c, callint.c, syntax.c, ymakefile:
+	Copy fake-DEFUNs from auxdoc.c into comments
+	preceding the real DEFUNs for the same functions.
+	auxdoc.c is no longer in use.
+
+	* fileio.c (Fread_file_name_internal):
+	[VMS only] Return t if file name is null string.
+
+1986-11-04  Richard M. Stallman  (rms at prep)
+
+	* buffer.c (Fget_buffer_create):
+	For default-major-mode = nil case, use fundamental-mode
+	if old buffer's mode name has a non-nil mode-class property.
+	Requires creating Qmode_class to hold the symbol mode-class.
+
+	* s-hpux.h: #undef HAVE_PTYS because of problems with
+	scheme running as an inferior on a pty.
+	jinx@prep requested this.
+
+	* lread.c (check_obarray & its callers): eliminate 2nd arg.
+	Also, don't confuse types int and Lisp_Object.
+	If invalid value matches Vobarray, store a valid Vobarray.
+
+	* editfns.c (Fformat): Don't use an initialization for tem
+	since it is a Lisp_Object and that can be a struct.
+
+	* minibuf.c (Ftry_completion, Fall_completions):
+	Use XFASTINT when testing `bucket' for nonzero or
+	setting it to zero.
+
+	* callint.c (Fcall_interactively): If visargs[i] is nil,
+	don't try to reference it as a string.
+
+	* doc.c (FSnarf_dcumentation):
+	Was assuming exec-path was a string.  Fixed to use
+	exec-directory instead, and to validate its data type first.
+
+1986-11-04  Richard Mlynarik  (mly at prep)
+
+	* m-isi.h => m-isi-ov.h
+
+1986-11-04  Richard M. Stallman  (rms at prep)
+
+	* buffer.c (init_buffer_once):
+	Avoid casts from int to Lisp_Object (which would lose
+	if NO_UNION_TYPE is not defined); use XFASTINT.
+
+1986-11-03  Richard Mlynarik  (mly at prep)
+
+	* xterm.c (stufflines):
+	Initialise signal mask.
+
+	* xterm.h:

+
+1986-10-30  Richard Mlynarik  (mly at prep)

+	* m-vax.h (USG-only changes):
+	#define NO_REMAP (I don't understand exactly why one needs to do
+	this -- is there an unexec bug?)
+	#define TEXT_START = 0, since C code can't access `start' symbol.
+
+	* lisp.h, sysdep.c, indent.c, m-att3b.h:
+	USG and att3bxxx changes from karl@ohio-state.arpa
+	Define NO_REMAP, undefine LD_SWITCH_MACHINE
+
+	* buffer.c (Fbuffer_local_variables):
+	Return correct values when buffer is selected-buffer
+
+	* keyboard.c (cmd_error):
+	non-zero exit status on error.

+
+	* window.c (Fset_window_hscroll):
+	Don't inhibit redisplay optimisations if hscroll is same.
+
+	* ymakefile:
+	rm ../etc/DOC to avoid make-docfile overwriting any files which
+	were linked to it (unix sucks)
+
+1986-10-28  Richard Mlynarik  (mly at prep)
+
+	* vmsmap.c, termcap.c, sysdep.c, config.h-dist:

+
+1986-10-27  Richard Mlynarik  (mly at prep)
+

+	Gould changes. (marick%cthulhu@gswd-vms.ARPA)
+
+	* gould-sigvec.s:
+	New file.
+

+	New file (for utx/32 2.0 and above)
+	Old file renamed m-ogould.h.  See etc/MACHINES
+	for more information.
+
+	* unexec.c (make_hdr):
+	Typo "#ifdef A_TXT_OFFSET" should be "A_TEXT_OFFSET"	
+
+1986-10-22  Richard Mlynarik  (mly at prep)
+
+	* keyboard.c, keymap.c:
+	Move Fexecute_extended_command from keymap.c to keyboard.c rather
+	than make kludgy static vars global.
+
+	In Fexecute_extended_command record `(this-command-keys)' and
+	`last-command' accurately.
+
+	* emacs.c (main), dispnew.c (init_display):
+	Add -nx flag, meaning to inhibit X windows and just run in the
+	current virtual terminal.  (Perhaps there should be a generic flag
+	to disable any special window-system code)
+	Add Vwindow_system variable.

+	* search.c (Fstring_match):
+	Do range-checking on `start' argument.
+
+1986-10-21  Richard Mlynarik  (mly at prep)

+	Share command code, and make that code use
+	{request,unrequest,init}_sigio
+
+	* term.c (init_display):
+	Determine whether we are under X by whether DISPLAY env var is
+	set, not by whether TERM is "xterm"
+
+	* xterm.c (x_term_init):
+	Remove (if (!initialized) ...) test.
+	Set Vxterm directly, rather than calling setxterm (flush latter)
+
+	* lread.c (various):

+	avoid user confusion.
+
+1986-10-17  Richard Mlynarik  (mly at prep)
+
+	* cmd.c, process.c:
+	Doc fixes from sjk 
+
+	* buffer.c (init_buffer_once):
+	Do x = (Lisp_Object) 1 instead of (int) x = 1 for benefit of vms
+	and pyramid compilers.
+
+	* minibuf.c (Ftry_completion):
+	Test (bucket), not (XSYMBOL (bucket)) since Lisp_Objects may not
+	be able to be 0 on some implementations.
+
+	* editfns.c (Fformat):
+	Have to duplicate doprnt's work of decoding the
+	format-string top ensure that don't die on (format "%s" 0)
+	Also, use prin1-to-string to get PR for random objects
+
+	* m-celerity.h:
+	HAVE_ALLOCA
+
+1986-10-16  Richard Mlynarik  (mly at prep)
+
+	* m-att3b.h:
+	New file -- replaces m-3b20.h
+
+	* alloca.c, fileio.c, indent.c, unexec.c, ymakefile:
+	Bugs and fixes for att3b (and usg)
+	Use a global static var rather than a local one
+	to record the last block allocated by alloca.
+
+	* fileio.c (Fverify_visited_file_modtime):
+	If a formerly-nonexistent file has been created since we ``found''
+	it, say there is a discrepancy.
+
+1986-10-14  Richard Mlynarik  (mly at prep)
+
+	* callint.c (Fprefix_numeric_value):
+	Doc typo.
+
+	* malloc.c, regex.c:
+	Nuke "#if defined..." for VMS
+
+1986-10-12  Richard Mlynarik  (mly at prep)
+
+	* xdisp.c (many functions):
+	Rearrange the way in which the mode-line stuff is hacked:
+	in particular, display_string doesn't have a special-case
+	for %-escapes -- this is now all done in display_mode_element.
+	This was necessary to make %M work correctly.
+	Also, fix a few bugs (buffer-name truncation could cause
+	core-dump)
+
+	Dike out global-minor-modes.  This wasn't actually being used by
+	anything (due to a bug) and wasn't even being initialised!
+	minor-mode-alist does what this thought it was doing.
+
+1986-10-11  Richard Mlynarik  (mly at prep)
+
+	* doc.c (FSnarf_documentation):
+	In CANNOT_DUMP case wasn't treating PATH_EXEC as a path --
+	now uses exec-path instead.	
+
+	* lisp.h:
+	Get rid of #if defined... for benefit of vms
+
+1986-10-09  Richard Mlynarik  (mly at prep)
+
+	* abbrev.c (Funexpand_abbrev):
+	Preserve position of point.
+
+1986-10-07  Richard Mlynarik  (mly at prep)
+
+	* s-hpux.h:
+	#define HAVE_PTYS
+
+	* alloca.c:
+	Make some attempt to work in the USG case where "#define static"
+	is done.
+
+	* keyboard.c:
+	#undef FIONREAD in HPUX (seems to be unimplemented or broken)
+	The only reason this ever seemed to work was because of a bug in
+	v17.
+
+	* sysdep.c (child_setup_tty):
+	HPUX was defaulting terminal speed to 300 baud.
+
+	* alloca.s:
+	New hp9000 C function calling sequence.
+
+	* fileio.c (Fexpand_file_name):
+	Fix bug in (expand-file-name ".." "/foo/")
+
+	* callint.c (Fcall_interactively):
+	Remove extreme weirdness of storing (int) "" where a Lisp_Object
+	was expected (in visargs)
+	Slighly more informative error message for bad interactive code
+	letter.
+
+	* abbrev.c (Funexpand_abbrev):
+	Was deleting length of original text rather than length of
+	expanded abbrev.
+
+	* abbrev.c (Fexpand_abbrev):
+	Add an Fundo_boundary so that undo works to unexpand
+	abbrevs.
+
+1986-10-03  Richard M. Stallman  (rms at prep)
+
+	* ymakefile: Make LIBS_STANDARD the last libs loaded.
+
+	* xterm.c: Load sys/types.h explicitly if xterm.h doesn't do it.
+
+	* keyboard.c (interrupt_signal):
+	Delete suprious `)' in HAVE_X_WINDOWS case.
+
+1986-10-03  Richard Mlynarik  (mly at prep)
+
+	* sysdep.c (sys_suspend -- fake suspend case)
+	Missing comment */ terminator
+
+1986-10-02  Richard Mlynarik  (mly at prep)
+
+	* search.c:
+	There may be `holes' in regexp registers after a match: consider
+	matching "z" against "\\(\\(xyzzy\\)\\|\\)\\(z\\)" -- then
+	register 2 is unmatched, whilst registers 0, 1 and 3 have matches.
+	Fix register-hacking code in Flooking_at, search_buffer,
+	Fmatch_data, Fstore_match_data.
+
+	* crt0.c:
+	HP200 floating-point (sigh -- needed for load-average)
+
+	* sysdep.c (HPUX perror):
+	Should be "perror" not "_perror" -- communication foulup, sorry.
+
+1986-10-01  Richard M. Stallman  (rms at prep)
+
+	* marker.c (Fcopy_marker): Was stupidly failing to put
+	the new marker on the buffer's chain.  Fix to go thru Fset_marker.
+	This really does fix the crashes in GC.
+
+	* sysdep.c (for HPUX): Define utimes and _perror as no-ops.
+
+	* marker.c (Fset_marker): If attempt to set marker
+	to point to a dead buffer, set it to point nowhere.
+
+	* buffer.c (Fkill_buffer): Clear out the buffer's markers chain.
+
+	* keyboard.c (interrupt_signal):
+	Turn off the double-C-g feature when running under X windows.
+
+1986-09-29  Richard M. Stallman  (rms at prep)
+
+	* search.c: search_regs elements are now the correct character
+	numbers or string indices.  1 is not added when they are used;
+	instead the values are corrected just after regex library returns.
+	The loops to do this exit at the first -1 (unused register).
+
+	* alloca.s: Convert HP9000 code to new assembler syntax.
+	Rename flag hp9000s200 to hp9000. [mly]
+
+	* crt0.c: Convert HP9000 code to new assembler syntax. [mly]
+
+	* buffer.c (Fdelete_buffer_internal): Unused; deleted.
+
+	* marker.c (unchain_marker):
+	Dump core if first marker on buffers marker list
+	does not have that buffer as its buffer.
+	May help find bug where after GC a buffer's first marker
+	was on the free list.
+
+	* keyboard.c (cmd_error): In -batch, die after error message.
+
+	* bytecode.c (Fbytecode):
+	Open-code Bvarref with one-byte arg.
+
+	* callproc.c (init_callproc): Use only first element of
+	Vexec_path to make Vexec_directory.  [mly]
+
+1986-09-28  Richard M. Stallman  (rms at prep)
+
+	* data.c (Fsymbol_value): use assq_no_quit instead of Fassq.
+	* fns.c (assq_no_quit): Like Fassq but never quits or gets errors.
+
+	* keyboard.c (quit_throw_to_get_char):
+	* eval.c (Fsignal):
+	Call quit_error_check.
+	* dispnew.c (quit_error_check):
+	Dump core if DesiredScreen is not full of zeros.
+	This is to catch the bug wherein DoDsp called from get_char
+	died because DesiredScreen was full of lines already.
+
+1986-09-26  Richard Mlynarik  (mly at prep)
+
+	* regex.c (re_match_2), search.c (various):
+	The registers modified by re_{search,match}{,_2}
+	now have start and end of -1 if that register was
+	not used in the match found.
+	Fmatch_data now returns a list of twice the number of registers
+	-actually- used (including register 0, for the whole match)
+
+	* process.c (Fwaiting_for_user_input_p):
+	New function for use by process-filters and sentinels
+	so they can determine if it might be an appropriate time
+	to try to make some sort of asynchronous notification.
+
+1986-09-26  Richard M. Stallman  (rms at prep)
+
+	* keymap.c (syms_of_keymap): Add missing defsubr
+	for Fdefine_prefix_command,
+
+	* abbrev.c (Fexpand_abbrev): Save original text of the abbrev
+	in Vlast_abbrev_text.
+	* abbrev.c (Funexpand_abbrev): Restore the original text.
+	Thus expand and unexpand preserves case.
+	Also, if there is no abbrev to unexpand, do nothing.
+	* abbrev.c (syms_of_abbrev):
+	Turn Lisp variables last-abbrev and last-abbrev-text back on.
+	* abbrev.c (Flast_abbrev_expansion): Delete this function.
+
+1986-09-25  Richard M. Stallman  (rms at prep)
+
+	* window.c (Fwindow_width): return a value one smaller
+	for partial-width windows that contain a | border.
+
+	* macros.c: Remove Fname_last_kbd_macro (moved to macros.el).
+
+1986-09-25  Richard Mlynarik  (mly at prep)
+
+	* unexec.c:
+	Include a.out.h before getpagesize.h, since EXEC_PAGESIZE
+	may be defined in a.out.h
+
+	* dispnew.c:
+	Only define TIOCOUTQ as TCOUTQ if the latter as defined,
+	so that ifdef conditionals on the former work as expected.
+
+	* sysdep.c (sys_suspend):
+	Needed to include buffer.h for getting cwd when doing a fake suspend.
+	  (for system v and other complete losers)
+	Rather than doing that include (which tickled some cretin-compiler
+	bugs) look up bf_cur->default_directory by
+	Fsymbol_value (Qintern ("..."))
+
+1986-09-24  Richard Mlynarik  (mly at prep)
+
+	* editfns.c (Fregion_beginning, Fregion_end):
+	Share common code (this doesn't have to be so fast that the
+	extra function-call could hurt)
+
+	* editfns.c, window.c, callint.c, buffer.c:
+	Don't allow bf_cur->mark to be nil.
+	Instead, to indicate that the mark is not set,
+	make the marker not point at anything.
+	This simplifies life quite a lot.
+
+	Add sanity checking in case user sets mark to point to different
+	buffer (he could do this by side-effecting (marker-mark) stupidly)
+
+	Change definition of marker-mark so that it returns a marker
+	object which doesn't point anywhere when there is no mark,
+	rather than nil.  This is more useful.
+
+	* editfns.c, bytecode.c.
+	Move set-mark, mark to lisp code.
+
+	* editfns.c (Fset_mark)
+	Not interactive.
+
+1986-09-23  Richard M. Stallman  (rms at prep)
+
+	* crt0.c, m-hp9000.h: rename hp9000s200 to hp9000.
+	* m-hp9000.h: New name for m-hp200.h.
+	* unexec.c (for hpux): define MY_ID from HP9000S200_ID
+	if that exists; else use model.h.
+	
+
+1986-09-21  Richard M. Stallman  (rms at prep)
+
+	* search.c (search_buffer): Fix backwards condition
+	in whether the translate table can be ignored.
+
+	* process.c (Fprocess_send_string): Name of function for Lisp
+	had a typo.
+
+	* eval.c: When looping getting the function definitions of
+	symbols, check for quit.
+
+	* lisp.h: Restore old declaration of `getenv'
+	since removing it causes warnings in many places.
+
+	* minibuf.c (scmp): Return correct value.
+
+1986-09-21  Richard Mlynarik  (mly at prep)
+
+	* editfns.c (Finsert_char):
+	New function.  There are a lot of places in lisp code
+	which want to insert multiple copies of a constant char.
+	This is a faster way of doing it, and doesn't cons
+	(unlike (insert (make-string n c)))
+
+1986-09-21  Richard M. Stallman  (rms at prep)
+
+	* process.c (make_process): Code to compute # elts in
+	vector to make a Lisp_Process had several errors:
+	Took size of pointer rather than of struct Lisp_Vector
+	and had wrong sign compensating for first element.
+
+	* fileio.c (directory_file_name): If arg is "/", return "/".
+
+1986-09-20  Richard M. Stallman  (rms at prep)
+
+	* minibuf.c (Fdisplay_completion_list):
+	New Lisp-callable function replaces minibuffer_completion_help_1,
+	with a little new feature: elements of the completion list
+	may be lists of two strings, and if so the two strings
+	are printed in immediate succession.
+
+1986-09-19  Richard Mlynarik  (mly at prep)
+
+	* minibuf.c (scmp and callers)
+	Don't be fazed by '\0' in strings.
+
+	* lisp.h, search.c, minibuf.c
+	Use downcase_table
+
+1986-09-18  Richard Mlynarik  (mly at prep)
+
+	* ymakefile, emacs.c, callproc.c, process.c, fns.c
+	Install MAINTAIN_ENVIRONMENT conditional to call environ.c.
+
+1986-09-16  Richard M. Stallman  (rms at prep)
+
+	* keymap.c (where_is_in_buffer): Fix bug in checking for shadowed
+	keys: do Flookup_key only on local map, and ignore value if
+	it is a number (that means key is locally undefined).
+
+1986-09-15  Richard Mlynarik  (mly at prep)
+
+	* buffer.c (Fbury_buffer)
+	Make this function interactive (bury current buffer)
+	Do error-checking on arg.
+
+1986-09-15  Richard M. Stallman  (rms at prep)
+
+	* emacs.c (main): Eliminate VMS -nl switch.
+	Instead, `-map FILE' says to map data file FILE;
+	no switch means don't map any file.
+	Can call mapin_data directly since exact file name is given.
+
+	* emacs.c (undump_emacs): Delete this.
+
+	* emacs.c (main): Make it work to use more than one of the
+	special switches (-batch, -t, -map).
+
+1986-09-14  Richard M. Stallman  (rms at prep)
+
+	* Renamings for VMS.
+	config.h.dist => config.h-dist
+	paths.h.dist => paths.h-dist
+	[ms]-*.*.h => [ms]-*-*.h
+	s-usg5.2.2.h => s-usg5-2-2.h
+
+	* Some new files for VMS.
+	compile.com, link.com, precomp.com, ccom.com,
+	testemacs.com, build.com are command files.
+	temacs.opt is a linker control file.
+	VMSBUILD gives info on how to use them.
+	README describes what this directory is for.
+
+1986-09-13  Richard M. Stallman  (rms at prep)
+
+	* sysdep.c (reset_sys_modes):
+	Delete never-used VMS & SIGIO conditional.
+	Call reset_sigio just once.  No need to clear FASYNC here
+	now that init_sigio makes sure it is clear in old_fcntl_modes.
+
+	* eval.c (top_level_value, top_level_set):
+	These are new names for Fglobal_value and Fglobal_set,
+	which are no longer callable from Lisp.
+	They are also commented out.
+
+1986-09-12  Richard Mlynarik  (mly at prep)
+
+	* xfns.c (Fx_rebind_key)
+	Fix typo.
+
+	* mocklisp.c:
+	Delete ml-substr.  Move to mlsupport.el
+
+	* buffer.c
+	The real work of setting up mode_line_default is done in
+	loaddefs.el.
+
+	* lread.c, data.c, marker.c, window.c
+	Flush the last callers of defalias.  Flush defalias.
+	(Use fsets in subr.el instead)
+
+1986-09-11  Richard Mlynarik  (mly at prep)
+
+	* emacs.c (main)
+	Under X, accept "-display" switch as synonym for "-d"
+
+	* eval.c (spedcbind)
+	Don't make Lisp_Buffer_Objfwd's buffer-local when just binding.
+	(so now (let ((case-fold-search t))) doesn't force buffer-localness)
+	However, setting a binding will still make it buffer-local.
+	(ie (let ((case-fold-search t)) (setq case-fold-search t))
+	 will cause case-fold-search be buffer-local even outside the let)
+
+	* xfns.c
+	Preserve studlycaps: "Gnuemacs" => "GNU Emacs"
+
+	* Various
+	Flush last users of LISTP => CONSP
+
+	* buffer.h
+	Make backed_up a Lisp_Object, since it is one!
+	Make abbrev_table a magic-local-variable.
+
+	* alloc.c (mark_buffer)
+	Simplify, simplify.
+
+	* buffer.h:
+	Reorder elements of struct buffer so that Lisp_Object
+	slots are contiguous from buffer.name through to the
+	end of the buffer.  All slots before buffer.name are
+	not Lisp_Objects (except buffer.markers, which is gc-magic)
+
+	Eliminate useless buffer.number slot.
+
+	* buffer.c (Fbuffer_number):
+	delete.	
+
+1986-09-10  Richard M. Stallman  (rms at prep)
+
+	* process.c (Fsend_{string,region}): rename as Fprocess_send...
+	and change names of Lisp function.  Old names now aliases in subr.el.
+
+1986-09-10  Richard Mlynarik  (mly at prep)
+
+	* buffer.c
+	New struct buffer_local_symbols.
+	staticpro buffer_defaults, buffer_local_symbols.
+
+	* lread.c (defvar_per_buffer)
+	Hack buffer_local_symbols
+
+	* buffer.c (Fbuffer_local_variables)
+	(a) Fcopy_alist so don't return any shared list structure
+	(b) Include names and values of Lisp_Buffer_Objfwd locals.
+
+	* alloc.c (FGarbage_collect):
+	Don't mark buffer_defaults specially, as it is now in staticvec
+
+	* dired.c (Fdirectory_files):
+	Optional third argument match is a regexp specifying
+	to only return files whose names contain a match for that regexp.
+	[eg ``(directory-files "/u2/emacs/" nil "\\`[^#]")'']
+
+1986-09-10  Richard M. Stallman  (rms at prep)
+
+	* alloc.c (Fgarbage_collect): Use open code instead of Fnthcdr
+	to avoid possibility of error.
+
+	* lread.c (Fload, load_unwind): The Lisp_Internal_Stream
+	now points to a word got with xmalloc and that points to the FILE.
+	On Elxsi, the FILE address is not in the part of the address
+	space that Lisp_Object pointers can reach.  New way can't lose.
+
+1986-09-09  Richard M. Stallman  (rms at prep)
+
+	* crt0.c: Add _start for elxsi.
+
+1986-09-07  Richard Mlynarik  (mly at prep)
+
+	* minibuf.c (read_minibuf)
+	gc-protect the saved data!
+	  I'm don't know why this doesn't just bind help-form
+	  (and current-prefix-arg) esp since there is already an
+	   unbind_to which would help us do this.
+	   Since I don't know why the `bindings' are done this way,
+	   I'm leaving the unwind-protect hair, and adding GCPRO hair.
+
+	* minibuf.c (read_minibuf, read_minibuf_unwind)
+	preserve the value of current-prefix-arg.
+
+	* minibuf.c:
+	Eliminate read_minibuf_string.
+	Move defalias for read-input to subr.el
+
+	* callint.c, fns.c, lisp.h
+	Call read_minibuf instead of read_minibuf_string.
+
+1986-09-04  Richard Mlynarik  (mly at prep)
+
+	* fns.c (Fy_or_n_p, Fyes_or_n_p)
+	Beep if the user types an invalid response.
+
+1986-09-03  Richard M. Stallman  (rms at prep)
+
+	* dispnew.c (update_screen):
+	Take out previous change.
+
+	* xdisp.c (DoDsp): Move call to request_sigio
+	after update: so it cannot be bypassed.
+
+	* sysdep.c (init_sigio): set old_fcntl_flags here
+	only once; don't change it in request_sigio.
+	* sysdep.c ({un,}request_sigio):
+	Set interrupts_deferred while SIGIO is unrequested.
+	Abort if FASYNC is already set when request_sigio is called.
+	* keyboard.c (get_input_pending):
+	Always do FIONREAD if interrupts_deferred.
+
+1986-09-01  Richard M. Stallman  (rms at prep)
+
+	* xterm.c/xfns.c: Many changes from rlk,
+	including using sigblock/sigsetmask to block signals
+	instead of turning handler off and on.
+
+	* dispnew.c (update_screen):
+	If interrupt input, wait while output gets written
+	before returning.  If observed loss of output really is
+	a kernel bug, this may make it stop.
+
+1986-08-31  Richard M. Stallman  (rms at prep)
+
+	* keymap.c (where_is_in_buffer):
+	Use Fequal rather than EQ to test for a match
+	if the object being searched for is a cons cell.
+
+1986-08-30  Richard M. Stallman  (rms at prep)
+
+	* data.c (Fsetq_default): new function.
+
+1986-08-28  Richard M. Stallman  (rms at prep)
+
+	* xdisp.c (display_mode_element):
+	Cons cell whose car is a symbol now means
+	(SYMBOL IF_TRUE_DISPLAY IF_FALSE_DISPLAY)
+	and is equivalent to IF_TRUE_DISPLAY if SYMBOL's value is non-nil
+	or to IF_FALSE_DISPLAY if SYMBOL is unbound or has value nil.
+	* buffer.c (syms_of_buffer): update documentation for that.
+
+1986-08-25  Richard M. Stallman  (rms at prep)
+
+	* fns.c (merge): Swap the arguments to the sort predicate
+	so as to use it to compute <= rather than <.
+	Sort had been anti-stable; now it is stable.
+
+	* editfns.c (Fuser_uid, Fuser_real_uid):
+	New functions that return values of geteuid and getuid system calls.
+
+	* dired.c (Ffile_attributes):  Value has additional element
+	t iff file gid would change if Emacs deletes it and recreates it.
+
+	* xdisp.c (display_mode_element):
+	If element is a list and its car is a list,
+	process all list elements recursively and concatenate them.
+	Makes alists work.
+
+	* xdisp.c (display_mode_string): New element type %n
+	prints ` Narrow' and ` Def' if appropriate.
+	* buffer.c (syms_of_buffer): Fix documentation of mode-line-format.
+
+	* undo.c (Fundo_more):
+	Fix bugs in checking len and pos for being in bounds.
+
+	* eval.c (Fuser_variable_p):
+	If documentation property is a number,
+	negative means it's a user variable.
+	* doc.c (Fdocumentation_property):
+	Use abs value of property as the file position.
+	* doc.c (FSnarf_documentation):
+	For variables, store negative property if string starts with `*'.
+
+	* editfns.c (Finsert_buffer_substring):
+	Implement inserting part of a buffer into itself.
+
+1986-08-24  Richard M. Stallman  (rms at prep)
+
+	* xterm.c, xfns.c, sink.h: Installed latest changes from
+	Athena, and fixed up formatting conventions.
+
+1986-08-23  Richard M. Stallman  (rms at prep)
+
+	* eval.c (unbind_catch): Restore gcprolist from the catchtag.
+
+1986-08-21  Richard M. Stallman  (rms at prep)
+
+	* fileio.c (barf_or_query_if_file_exists):
+	New second arg non-0 says query; do not call Finteractive_p.
+
+	* fileio.c (Frename_file, Fcopy_to_file, Fadd_name_to_file,
+	Fmake_symbolic_link):
+	Interactive spec now says `p' for the third arg.
+	If third arg is number, do call barf_or_query_if_file_exists
+	but pass nonzero second arg in that case.
+
+	* eval.c (Finteractive_p): Skip the innermost frame
+	when examining the stack.  This makes the right thing happen
+	if called from Fbyte_code.
+
+1986-08-21  Richard Mlynarik  (mly at prep)
+
+        * process.c (handle_process_output):
+	do a set-buffer back to original buffer
+	after calling a process' filter function so that
+	all filter functions needn't save-excursion.
+
+	* keymap.c (where_is_in_buffer):
+	Don't blow out if buffer has no local map.
+
+1986-08-21  Richard M. Stallman  (rms at prep)
+
+	* emacs.c (main): Eliminate references to environ.c.
+
+	* callproc.c (Fcall_process): Pass child_setup
+	the standard Unix environment.
+	* process.c (create_process): likewise.
+
+	* bytecode.c (Fbyte_code): At end, abort if specpdl
+	is not back to same level it had on entry.
+
+	* eval.c (unbind_catch):
+	New way to unbind for throw.  Pops catches, handlers
+	and bindings, in one synchronized pass.  Thus, when an
+	unwind-protect is executed, all catches and handlers
+	outside of it are still in effect.
+	Also restore various static variables from the catchtag
+	being unbound.  struct catchtag has two new fields,
+	gcpro and pdlcount.
+
+	* eval.c (Fthrow, Fsignal):  Use unbind_catch before longjmp.
+
+	* eval.c (internal_catch): No need to restore anything
+	from the catchtag after throw, because unbind_catch does it all.
+	Must set up pdlcount and gcpro fields.
+	* eval.c (internal_condition_case, Fcondition_case):
+	Changed like internal_catch.
+	* eval.c (Fcatch): use internal_catch to do the work.
+
+	* eval.c (Fsignal): If no handler applies, try calling
+	the Lisp debugger; if that fails, throw to top-level.
+	Don't call `debugger'.
+
+	* keyboard.c (debugger): Delete this function.
+
+1986-08-20  Richard M. Stallman  (rms at prep)
+
+	* Gap motion can now quit!
+
+	* insdel.c (move_gap): new name for GapTo.  Callers changed.
+
+	* insdel.c (InsCStr):
+	* fileio.c (Finsert_file_contents):
+	Call move_gap before calling record_insert.
+	* insdel.c (del_range):
+	Don't adjust point until after all possible errors detected,
+	which means after gap is moved.
+
+	* insdel.c (gap_right, gap_left):
+	Check every 32000 chars for pending quit.
+	Also speed up char-copy inner loop.
+
+	* lisp.h (QUITP): New macro, nonzero if ought to quit now if poss.
+
+1986-08-20  Richard M. Stallman  (rms at prep)
+
+	* undo.c (Fundo_more):
+	Fix bug that was setting point to `len' field, not `pos' field.
+	Share the error-checking code between all three types of
+	undo record that actually make changes.
+
+	* xdisp.c (display_mode_element):
+	Fix a couple of silly bugs.
+
+	* lread.c: New variable-defining functions
+	defvar_int, defvar_lisp, defvar_bool and defvar_per_buffer
+	are called by the new DEFVAR... macros.  They ignore the
+	doc-string argument.
+
+	* lisp.h: Define macros DEFVAR_LISP, DEFVAR_INT, DEFVAR_BOOL
+	and DEFVAR_PER_BUFFER.  They expand into calls to
+	defvar_lisp, etc.
+
+	* all .c files:
+	All Def...Var renamed to DEFVAR... in syms_of_....
+
+	* doc.c (FSnarf_documentation): Understand new DOC format
+	where doc for function foo is named Ffoo and doc for variable foo
+	is named Vfoo.  When doc for a variable is found, store the
+	file-position in DOC on the variable-documentation property.
+	* doc.c (Fdocumentation_property): New Lisp function,
+	like `get' except that if the value is a positive integer
+	it is taken as a position in the DOC file and a string is read
+	from that file.
+
+	* filelock.c: correct spelling "supercession" -> "supersession".
+
+	* undo.c: Rename RecordInsert as record_insert, and
+	likewise RecordDelete, RecordChange and RecordChange1.
+	* casefiddle.c, editfns.c, fileio.c, insdel.c: change callers.
+
+1986-08-19  Richard M. Stallman  (rms at prep)
+
+	* xdisp.c (display_mode_element):
+	Change the interpretation of symbols and lists in elements:
+	if a symbol's value is a string, output that string literally;
+	a list is a concatenation of all elements if the car is a string
+	or a conditional of the cdr if the car is a symbol.
+
+	* undo.c (Record...):
+	Remember buffer->modtime as the "length" of the Uunmod.
+	If point is at the end of a range deleted or changed,
+	record that as the "position" of the range and make the length
+	negative.
+
+	* undo.c (Fundo_more):
+	Undoing Uunmod does not mark as unmodified unless its
+	remembered modtime matches the buffer's current modtime.
+	Also handle case where length is negative in Uinsert, Uchange.
+
+1986-08-18  Richard Mlynarik  (mly at prep)
+
+	* xdisp.c (display_mode_line):
+	XSTRING->data, not XSTRING
+	Fix another typo.
+
+1986-08-17  Richard M. Stallman  (rms at prep)
+
+	* buffer.c (syms_of_buffer):
+	Change doc for mode-line-format.
+
+	* xdisp.c (display_mode_line, display_mode_element):
+	Allow buf->mode_line_format to contain lists and symbols
+	allowing computation and concatenation to produce the mode line.
+	(Note that evaluation is not allowed; it would be unsafe.)
+	display_mode_element is the recursion point for this.
+
+1986-08-17  Richard Mlynarik  (mly at prep)
+
+	* emacs.c (main)
+	Move init_environ up.
+
+	* window.c (Fwindow_point)
+	typo.	
+
+	* environ.c
+	New function getenv replaces un*x getenv
+
+1986-08-17  Richard M. Stallman  (rms at prep)
+
+	* window.c (Fwindow_point):
+	When WINDOW is the selected window and its buffer is selected too,
+	return current value of point.  The pointm field of the window
+	is not meaningful in such cases.
+
+	* unexec.c (write_segment):
+	If hit nonexistent page, must write zeros, not return.
+
+1986-08-17  Richard Mlynarik  (mly at prep)
+
+	* callproc.c, process.c (Fcall_process, create_process)
+	Use `alloca' versions of environment-hacking functions
+	(ie current_environ_size and get_current_environ rather than
+	current_environ and free_environ)
+
+	* emacs.c (main):
+	Call syms_of_environ, init_environ.
+
+	* config.h., config.h.dist
+	Increase PURESIZE again (sigh)	
+
+	* unexec.c (write_segment):
+	Kludgey coercions ("(int)") to get this line to compile:
+         nwrite = (((int) ptr + 128) & ~127) - (int) ptr;
+	Also changed incorrect ~128 to ~127.
+
+	* process.c:
+	New function Fprocess_list.
+
+1986-08-17  Richard M. Stallman  (rms at prep)
+
+	* crt0.c, alloca.s: Remove hack_sky (special for sun2)
+	and the call to it.  No longer needed since floating point
+	is no longer used.
+
+	* unexec.c: New compiler flag A_TEXT_OFFSET is defined
+	for machines in which the a.out file header counts as the
+	first few bytes of the text segment.  The definition of
+	A_TEXT_OFFSET would normally be sizeof (HDR).  It has
+	other terms added in on some machines (sequent).
+
+1986-08-16  Richard Mlynarik  (mly at prep)
+
+	* eval.c (Fmacroexpand)
+	Use car of nthcdr, not nth.
+
+	* fns.c
+	Define Fcopy_alist (used to be in subr.el)
+	Move Fnth to subr.el
+
+	* ymakefile
+	Include environ.c
+
+	* callproc.c, process.c (child_setup, Fcall_process, create_process):
+	Take/pass environment arg.
+
+	* environ.c:
+	New file
+
+	* sysdep.c:
+	Move VMS sys_getenv to environ.c
+
+	* editfns.c:
+	Move getenv to environ.c
+
+1986-08-16  Richard M. Stallman  (rms at prep)
+
+	* xdisp.c (display_text_line):
+	* indent.c (current_column, ToCol, position_indentation):
+	* indent.c (Fmove_to_column, compute_motion):
+	Bring tab_width in range if it is very large.
+
+1986-08-15  Richard M. Stallman  (rms at prep)
+
+	* fileio.c (Fwrite_region):
+	Do the fsync before the fstat; that may prevent what appear
+	to be spurious "file has changed on disk" warnings.
+	Update bf_cur->modtime before signaling "IO error writing"
+	to avoid more such warnings.
+
+	* Make ctl-arrow, case-fold-search, etc. behave exactly
+	as if they had been made local with make-variable-buffer-local.
+	The default values live in struct buffer buffer_defaults.
+	They also live in buffers that do not have local values.
+	Each buffer has a local_var_flags slot with a bit for each
+	variable, saying which variables are local in that buffer.
+
+	* buffer.h: New buffer slot local_var_flags.
+	* buffer.c: New structures buffer_defaults and buffer_local_flags.
+	(init_buffers_once): store default values for local slots
+	into buffer_defaults.
+	(reset_buffer_variables): Copy default values from buffer_defaults
+	into the buffer being reset.
+	(syms_of_buffer): Variables default-ctl-arrow, etc., now
+	forward to slots in buffer_defaults.
+
+	* data.c (Fset, Fset_default, Fdefault_value,
+	Fkill_local_variable):
+	Know that a Lisp_Buffer_Objfwd has default value
+	if the buffer_local_flags slot is nonzero,
+	and a buffer uses that default unless its local_var_flags
+	contains the bit of the buffer_local_flags for the slot.
+
+	* alloc.c (Fgarbage_collect): Call mark_buffer on buffer_defaults.
+
+1986-08-14  Richard M. Stallman  (rms at prep)
+
+	* unexec.c (copy_text_and_data):
+	Write text and data separately if COFF (just as if not COFF).
+	(make-hdr): if COFF and NO_REMAP, don't alter some f_ohdr fields.
+
+1986-08-14  Richard Mlynarik  (mly at prep)
+
+	* editfns.c (getenv)
+	Make getenv useful interactively.
+	Move defaliases to fsets in subr.el
+
+1986-08-14  Richard M. Stallman  (rms at prep)
+
+	* unexec.c: unexec_data_start records the ultimate
+	corrected data_start from make_hdr; copy_text_and_data
+	starts writing data segment from that address.
+
+1986-08-13  Richard M. Stallman  (rms at prep)
+
+	* buffer.c (Fkill_buffer): Combine Fdelete_buffer_internal
+	into this function.  Simplify.  Just return immediately
+	if attempted to kill the minibuffer.
+
+	* lisp.h: Define XSETPNTR and make XSETCONS (etc) use it.
+	By default XSETPNTR is the same as XSETUINT.
+
+	* lread.c (oblookup, map_obarray):
+	Use XUINT, not XSYMBOL, to check for zero to detect end of bucket.
+	On machines where all pointers have high bits set,
+	XSYMBOL would never return zero.
+
+	* alloc.c: change vars most_negative_fixnum and dont_copy_flag
+	to constant macros ARRAY_MARK_FLAG and DONT_COPY_FLAG,
+	defined normally based on INTBITS but overridable by m-*.h.
+
+	* process.c (handle_process_output):
+	Write in buffer even if buffer is read-only.
+
+	* fileio.c (barf_or_query_if_file_exists):
+	Rearrange: don't use comma around calls to NULL,
+	so can compile using union type.
+
+1986-08-12  Richard Mlynarik  (mly at prep)
+
+	* buffer.c (SetBfp, syms_of_buffer)
+	Dike out debug-check-symbol code.  I believe that this bug has
+	evaporated.
+
+	* fileio.c (barf_or_query_if_file_exists)
+	! => !NULL.  Also use local variable for Lisp_object for bd
+	compilers.
+
+1986-08-11  Richard Mlynarik  (mly at prep)
+
+	* buffer.c (Fbarf_if_buffer_read_only)
+	Include buffer in call to Fsignal.
+
+	* print.c (Fwrite_char)
+	Really default stream to standard-output.
+
+1986-08-10  Richard Mlynarik  (mly at prep)
+
+	* eval.c (and abbrev.c, buffer.c, callint.c, cmds.c, keyboard.c, lread.c, lisp.h)
+	Allow Fapply to take an &rest arg, the last of which is spread.
+	(So (apply '+ 1 '(2 3)) => 6)
+	Make Ffuncall do the work for Fapply, rather than duplicating all
+	that code.  Define apply1 for c code which needs it.  Define call0
+	for c code which thought it needed Fapply.
+
+1986-08-08  Richard Mlynarik  (mly at prep)
+
+	* ymakefile
+	Don't assemble alloca.s if HAVE_ALLOCA.
+	Even though the whole of this file is contained in a
+	`#ifndef HAVE_ALLOCA ... #endif' a disgusting bug
+	in cc (at least here, vax 4.2bsd) meant that this
+	file was being assembled even though cc was passed
+	the -E flag!  Gag me with a unix-pinhead.
+
+	* m-vax.h
+	Define HAVE_ALLOCA if BSD
+
+	* unexec.c (write_segment)
+	Rename variable `fd' to `new' for macro PERROR.
+
+1986-07-30  Richard M. Stallman  (rms at prep)
+
+	* fileio.c (Fwrite_region): add call to fsync before close.
+
+	* xdisp.c (redisplay_window): Don't look at ->start
+	in windows that have subwindows, since it is nil there.
+
+	* window.c (save_window_restore):
+	Avoid doing Fset_buffer on a dead buffer.
+	Use the selected window's new current buffer in that case.
+
+1986-07-28  Richard M. Stallman  (rms at prep)
+
+	* fileio.c (Finsert_file_contents):
+	Don't mark buffer modified if inserted a null file.
+
+	* fileio.c (Fcopy_file, e_write): Use 16k buffer size.
+
+1986-07-17  Richard M. Stallman  (rms at prep)
+
+	* unexec.c (copy_sym): Put in missing #endif.
+
+	* alloc.c (Fpurecopy, mark_object): Flush VIRT_ADDR_VARIES
+	conditional; always use range from pure to pure + PURESIZE.
+	Use type PNTR_COMPARISON_TYPE as the type to compare in.
+	This is normally unsigned int but m- file may override this.
+
+	* lisp.h (CHECK_IMPURE): Use PNTR_COMPARISON_TYPE, and always
+	use the range from pure to pure + PURESIZE unless
+	PNTR_COMPARISON_TYPE is defaulted.
+
+	* eval.c (unbind_to): New temporary var `tmp'
+	to avoid a Gould compiler bug.
+
+	* term.c (calculate_ins_del_char_costs):
+	* window.c (change_window_height):
+	Changed floating point arithmetic to fixed point.
+
+	* sysdep.c: Replace ad-hoc conditionals with new flags
+	HAVE_VFORK, HAVE_DUP2 and HAVE_GETTIMEOFDAY.
+	Change s-hpux.h and m-stride.h.
+
+	* sysdep.c (init_sys_modes for VMS): Set TT2$M_XON.
+
+	* process.c (create_process): On USG systems that have TIOCNOTTY,
+	do the setpgrp here before reopening the pty rather than
+	waiting for child_setup.
+
+	* window.c (make_window): size given to make_vector
+	was one too small.
+
+1986-07-10  Richard M. Stallman  (rms at prep)
+
+	* keymap.c (Fdescribe_bindings): change XSETTYPE/XSETBUFFER to
+	XSET.
+	(describe_command): change XSETSTRING to XSET.
+	* window.c (Fmove_to_window_line): delete unused start =.
+	* xdisp.c (DoDsp) delete unused all_windows initializer.
+	* dispnew.c (update_line): delete unused osp =.
+	* minibuf.c (do_completion): delete unused completedp initializer.
+	* search.c (Freplace_match): delete unused some_multiletter_word init.
+	* alloc.c (gc_sweep): delete unused next initializers.
+	* fns.c (concat): after error on non-int elt for string,
+	   do store the new value from the error handler.
+	* lread.c (read1): comment out unused end =.
+	* lread.c (read_list): delete unused tail =.
+	* data.c (Fmake_variable_buffer_local):
+	  if value type is Lisp_Some_Buffer_Local_Value,
+	  change it to Lisp_Buffer_Local_Value permanently.
+	* undo.c (record_block): delete unused cp =.
+	  Don't bother reallocing if n = 0 after first batch.
+	* fileio.c (Fverify_visited_file_modtime):
+	  If CHECK_BUFFER changes buf, use the changed value.
+
+1986-07-07  Richard M. Stallman  (rms at prep)
+
+	* alloc.c (mark_buffer): mark the selective_display_ellipses slot.
+
+1986-06-25  Richard M. Stallman  (rms at prep)
+
+	* window.c (Frecenter): Fix bug in last change:
+	change applied to M-- arg ratherthan C-u by mistake.
+
+1986-06-19  Richard M. Stallman  (rms at prep)
+
+	* ymakefile (CPP): Now defined by default as `cc -E'.
+	* Makefile: likewise.
+
+	* More 3b changes:
+	* ymakefile: Allow config to specify LIBS_TERMCAP even if
+	TERMINFO.
+	* sysdep.c: Delete the sign-extension functions; just define
+	a variable sign_extend_temp.
+	* m-3b.h renamed to m-3b20.h.  Now defines ATT3B20 as well as
+	ATT3B.  New definitions for XINT and SIGN_EXTEND_CHAR.
+
+	* sysdep.c (readdirver): New VMS-only function:
+	like readdir but return each version as separate filename.
+
+	* dired.c (file_name_completions): New arg ver_flag.
+	All callers changed.
+	* dired.c (Ffile_name_all_versions): New function, VMS only.
+
+	* unexec.c (copy_sym): Remove spurious #else on
+	sun3 conditional.  The old #else code is now unconditional.
+
+	* window.c (Fdisplay_window): Split largest window only if
+	full screen width.  The conditional was backwards.
+
+1986-06-17  Richard M. Stallman  (rms at prep)
+
+	* process.c (Fsend_region): Previous change forgot to assign
+	anything to start1.
+
+1986-06-13  Richard M. Stallman  (rms at prep)
+
+	* emacs.c (Fdump_emacs): Use start_of_text, not &_start,
+	as entry address for unexec.
+
+	* alloc.c: Use XPNTR, not XUINT, when checking for pureness.
+
+	* data.c: When indirecting through Lisp_Buffer_Objfwd,
+	use XUINT to get the offset, not XOBJFWD.
+
+	* lisp.h: New macro XPNTR is used as subroutine by all of
+	XCONS, XSTRING, etc.  Define it like XUINT normally.
+	If DATA_SEG_BITS is defined, XPNTR or's that into the result.
+	Use XPNTR in CHECK_IMPURE.
+
+	* sysdep.c (end_of_{text,data}): Do compile these.
+	rt-pc unexec needs them.
+	* sysdep.c (start_of_bss): New function.
+
+	* unexec.c (copy_text_and_data, write_segment):
+	Write text and data segments separately.
+	Use new subroutine write_segment to do each one.
+
+	* process.c (Fprocess_exit_status):
+	New name for Fprocess_reason.
+
+1986-06-11  Richard M. Stallman  (rms at prep)
+
+	* abbrev.c (Fexpand_abbrev):
+	Delete the - inserted by abbrev-prefix-mark, if any.
+
+	* filelock.c (lock_file):
+	Check for modifying a buffer whose file has changed
+	and call ask-user-about-supercession-threat, which can
+	ask for confirmation and get an error.
+
+1986-06-10  Richard M. Stallman  (rms at prep)
+
+	* crt0.c: Merge changes for Nu.
+
+	* unexec.c (make_hdr): Fix handling of blockcopy_start;
+	for the sake of Nu machine.
+
+	* fileio.c (Fcopy_file): optional 4th arg non-nil
+	means preserve the last-modified time.
+
+	* Make C-M-v in minibuffer scroll the minibuffer's help window if any.
+	* window.c (save_window_{save,restore}):
+	Save and restore minibuf_scroll_window.
+	* window.c (Fscroll_other_window):
+	If minibuffer is selected, scroll minibuf_scroll_window.
+	* minibuf.c (read_minibuf): set minibuf_scroll_window to nil.
+
+	* window.c (Frecenter): With just C-u as arg,
+	recenter point but don't erase the screen.
+
+1986-06-09  Richard M. Stallman  (rms at prep)
+
+	* process.c (Fsend_region):
+	* fileio.c (Fwrite_region):
+	* editfns.c (Fchar_after, save_restriction_restore):
+	Avoid using XINT in args to other macros.
+
+	* sysdep.c: New function char_sign_xtnd for ATT3B.
+
+	* lisp.h: Don't redefine XINT if it's already defined.
+	So m-3b.h can override it.
+
+	* ymakefile: If NO_REMAP, use the standard crt0.o
+	but precede it with pre_crt0.o whose job is to define data_start.
+
+	* buffer.h. buffer.c: New per-buffer variable 
+	selective-display-ellipses.
+
+	* xdisp.c (display_text_line), indent.c (compute_motion):
+	Let bf_cur->selective_display_ellipses control display of ...
+	before invisible lines.
+
+	* lread.c (openp, Fload): openp now takes a sequence
+	of suffixes with colons between.  It loops over
+	suffixes faster than over directories.
+	load takes new fourth arg NOSUFFIXES.
+
+1986-06-08  Richard M. Stallman  (rms at prep)
+
+	* paths.h: Remove . from load-path.
+
+	* lread.c: Make "load" no longer interactive.
+
+	* keyboard.c: Introduce BUFFER_SIZE_FACTOR to make
+	some keyboard buffers 16 times as big when X windows exist.
+
+1986-06-07  Richard M. Stallman  (rms at prep)
+
+	* eval.c (call_debugger): Don't do a debug-on-call
+	for calling the debugger.
+
+	* keyboard.c (gobble_input): Must really use FIONREAD.
+
+	* keyboard.c (command_loop{,_1,_2}, top_level_{1,2}):
+	Now Frecursive_edit calls command_loop, which does the catches
+	and calls command_loop_2, which does the error handling,
+	which calls command_loop to do the real work.
+	Also, top_level_1 does a condition-case around top_level_2,
+	which does the work.
+
+	Previously, the error handling was outside the catch for
+	top-level.  Then if handling an error ran an unwind protect form,
+	the catch was not in effect; so ^G, or the debugger Q command,
+	would not work inside of them.
+
+1986-06-06  Richard M. Stallman  (rms at prep)
+
+	* keymap.c (get_keymap{,_1}):
+	Create get_keymap_1 that takes arg saying whether to get error.
+	get_keymap calls that, saying do get an error.
+
+	* keyboard.c (get_char):
+	If rereading a char, do put it in the echo buffer
+	if the echo buffer is empty.  Fixes problem that
+	C-s C-h would never echo the C-h.
+
+	* window.h: New window slot start_at_line_beg,
+	holds t if window's start was the beginning of a line.
+	* window.c: update this wherever ->start is updated.
+	(But not always correctly).
+	* xdisp.c (redisplay_window): update start_at_line_beg,
+	and also find a new start if the old start used to be
+	a line beginning but no longer is (which implies text
+	changes just before it).
+
+	* keyboard.c (get_input_pending):
+	Don't bother with FIONREAD if interrupt_input;
+	just use kbd_count.
+
+	* fns.c: Assume KERNEL_FILE, LDAV_SYMBOL and NLIST_STRUCT
+	are fully set up by the s- and m- files.
+
+	* emacs.c (main): Don't call `signal' if in batch mode
+	and not initialized and dumping is possible.
+	* keyboard.c (init_keyboard): likewise for SIGIO.
+
+	* unexec.c (make_hdr): Copy entire header of old file
+	as base for header of new file.  Eliminates most
+	machine-specific conditionals.
+
+	* terminfo.c: make tparam work by calling tparm.
+
+	* term.c, cm.h: Eliminate `Tab' macro.
+
+	* s-usg5.2.h, s-usg5.2.2.h: set the TERMINFO flag.
+
+	* fileio.c (Ffile_newer_than_file_p): New Lisp primitive.
+
+	* fileio.c (Ffile_exists_p):  this is now distinct from
+	Ffile_readable_p; it checks only for existence, not for
+	readability.
+
+	* editfns.c (Fgoto_char): Use new interactive code N.
+
+	* callint.c (Fcall_interactively): New code N
+	means use prefix argif have one, else read number from minibuffer.
+
+	* buffer.c (record_buffer):
+	Don't use Frassq, Fmemq or Fdelq since their loops
+	allow quitting.  Write a spacial loop by hand.
+
+1986-06-05  Richard M. Stallman  (rms at prep)
+
+	* process.c: Add MASSCOMP conditionals for pty and tty names.
+	New way to check pty accessibility with `access'.
+
+	* unexec.c (make_hdr): MASSCOMP has its own special field.
+
+	* sysdep.c: Use HAVE_TERMIO conditionals instead of USG
+	conditionals in many places.  Use INTERRUPTABLE_OPEN
+	and INTERRUPTABLE_IO conditionals to decide whether to
+	include the functions sys_read, sys_write, sys_open.
+	child_setup_tty must do FIOASYNC on masscomp.
+
+	* fns.c (concat): Add MASSCOMP_REGISTER_BUG conditional.
+
+	* editfns.c (init_editfns): Always check LOGNAME if no USER var.
+
+	* dispnew.c: Now depends on HAVE_TERMIO.
+
+	* crt0.c: BOGUS flag renamed CRT0_DUMMIES.  Also now
+	this is never assumes; each m- file must set it to use that code.
+
+	* crt0.c: Two new flags: GLOBAL_START_DOT and
+	GLOBAL_START_NO_DOT, control .globl start, etc.
+	m- files must define these as needed.
+	To have no effect, must define one or the other whenever
+	CRT0_DUMMIES is set except for masscomp.
+	GLOBAL_START_NO_DOT for tower32, GLOBAL_START_DOT for all others.
+
+	* term.c, termchar.h: Define new flag var no_redraw_on_reenter;
+	nonzero means no need to set screen_garbaged on resuming
+	after a suspension.
+	* sysdep.c (init_sys_modes): don't set screen_garbaged
+	after resumption if that flag is set.
+	* dispnew.c (syms_of_dispnew): make Lisp var no-redraw-on-reenter,
+
+	* process.c (Fprocess_reason): New function.
+
+	* dispnew.c (change_screen_size): New arg PRETEND.
+	If it's zero, set ScreenRows or ScreenCols.
+	Fset_screen_{width,height} take new arg as well
+	to control value of PRETEND.
+
+	* sysdep.c (child_setup_tty for USG):
+	Turn ICANON on, and set VKILL and VERASE to 0377.
+	Don't frob VMIN and VTIME (said to be unnecessary here).
+
+	* keyboard.c (command_loop, Frecursive_edit):
+	Call top_level_1 only from command_loop.
+	Do it before command_loop_1.  Put catch for top-level around it.
+
+	* xdisp.c (try_window_1): use scroll_cost to decide
+	whether scrolling, as determined from ins/del records,
+	is better than simple reprinting.
+
+	* scroll.c (scroll_cost): New function computes what cost
+	would be to do scroll_screen_lines.
+
+	* xdisp.c (display_text_string):
+	Display minibuf_prompt only if vpos is the top of the minibuffer.
+	Attempts to fix the bug where the prompt appears on all the
+	lines of an empty minibuffer.
+
+1986-06-04  Richard M. Stallman  (rms at prep)
+
+	* fileio.c (Fdefine_logical_name):
+	For VMS: create a logical name translation.
+
+	* emacs.c (main):
+	(HAVE_X_WINDOWS) New variable alternate_display,
+	set with a -d switch.
+
+	* keyboard.c, sysdep.c:
+	Create new system-independent function sys_suspend.
+	All places that want to suspend now use sys_suspend.
+	Delete fake_suspend and make its definition one of the
+	cases for sys_suspend; but require the caller to change
+	the terminal modes, on all system versions.
+
+	* Merged in VMS conditionals in numerous files.
+
+1986-06-01  Richard M. Stallman  (rms at prep)
+
+	* emacs.c (main, Fdump_emacs):
+	Use new arg to malloc_init to say what function to call for
+	warnings.
+
+	* unexec.c, malloc.c, getpagesize.h:
+	The code to define getpagesize () is now in getpagesize.h.
+
+	* process.c (reate_process), callproc.c (child_setup):
+	Move call to child_setup_tty from child_setup to create_process,
+	so it's not done for synchronous subprocesses.
+	* sysdep.c (child_setup_tty): omit it if not subprocesses.
+
+	* alloc.c (mark_object), lread.c (DefLispVar):
+	Protect the C variable with staticpro.
+	Therefore no more need to mark thru a Lisp_Objfwd.
+
+See ChangeLog.1 for earlier changes.
