# There are two files, reserved and special, which contain the names of
# strings which must not be remapped. In general, reserved contains strings
# which are meaningful to the C preprocessor or compiler, and "special"
# contains special emacs strings that must not be remapped (they are the
# basename of an include file for example; actually this is a holdover from
# when sed or m4 was used to do the remapping, not needed with cpp remapping).
#
# Note, because "cut" is braindamaged and does not return explicit status,
# and since the status returned to make is that of the last program in the
# pipeline, we filter the final result through cat to avoid killing make.
