5456 autoconf. If HAVE_UNISTD_H is defined, include unistd.h to get
5457 appropriate definitions of read, write, etc. Add prototype for
5458 system.
5459
5460Tue Feb 4 13:24:44 1997 Doug Evans <dje@canuck.cygnus.com>
5461
5462 * Makefile.in (libcommon.a): Delete.
5463 (callback.o,targ-map.o): Delete, moved to Make-common.in.
5464 (gentmap,targ-vals.h,targ-map.c): Likewise.

5480 comments and single quotes. Fixes a problem found on hpux.
5481
5482Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
5483

5487 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in

5489 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5490 targ-map.o, and run are built. They are now built in the
5491 individual simulator directories, taking sources from ../common as
5492 necessary. This replaces the merging of libcommon.a into
5493 linsim.a, which was problematic for the WinGDB build process.
5494 * run.c: Include config.h from . instead of ../common.
5495 * Make-common.in: Remove. It's no longer necessary.

5567
5568 * run.c (main): Removed SH specific comments, so source is
