There should be a copy of it + * somewhere on your system (see below). + * + * This header file, and a _minor_ change to + * config.h-dist are all that are needed to build GNU + * Emacs-18.58 on a Bull DPX/2 model 200 or 300. + * The DPX/2 500 should probably use a mips based config. + * + * The only change _needed_ to config.h (copied from + * config.h-dist) is to define the appropriate ncl_{el,mr} + * pre-processor constant. Hopefully in a future release + * the C compiler will define this automagically :-) + * + * If you have INET and X11 loaded, define HAVE_X_WINDOWS + * before you include this file. If you have INET but not + * X11 loaded define HAVE_SOCKETS in config.h before you + * include this file. + * + * If you make changes to this file, please be sure to send + * an update to me: <sjg@melb.bull.oz.au> + * + * Please read through this file before attempting to build + * Emacs. You may need to set SRC_COMPAT=_SYSV in your + * environment or in Makefile. + * + * + * AMENDED: + * 92/02/06 12:53:06 (sjg) + * + * RELEASED: + * 92/02/06 12:53:07 v1.7 + * + * BUGS: + * There is a problem when running Emacs with its own X + * window in that if the invoking process terminates, + * Emacs will terminate shortly afterwards. The following + * exercises the bug: + * $ ksh + * $ emacs & + * $ exit + * The emacs process will die within a few minutes of the + * invoking ksh's termination. Solution? Don't do the + * above :-) + * + * SCCSID: + * @(#)m-dpx2.h 1.7 92/02/06 12:53:06 (sjg) + */ + +/* + Copyright (C) 1985, 1986 Free Software Foundation, Inc. + +This file is part of GNU Emacs. + +GNU Emacs is free software; you can redistribute it and/or modify +it under the terms of the GNU General Public License as published by +the Free Software Foundation; either version 1, or (at your option) +any later version. + +GNU Emacs is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
