5058 autoconf. If HAVE_UNISTD_H is defined, include unistd.h to get
5059 appropriate definitions of read, write, etc. Add prototype for
5060 system.
5061
5062Tue Feb 4 13:24:44 1997 Doug Evans <dje@canuck.cygnus.com>
5063
5064 * Makefile.in (libcommon.a): Delete.
5065 (callback.o,targ-map.o): Delete, moved to Make-common.in.
5066 (gentmap,targ-vals.h,targ-map.c): Likewise.

5082 comments and single quotes. Fixes a problem found on hpux.
5083
5084Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
5085

5091 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5092 targ-map.o, and run are built. They are now built in the
5093 individual simulator directories, taking sources from ../common as
5094 necessary. This replaces the merging of libcommon.a into
5095 linsim.a, which was problematic for the WinGDB build process.
5096 * run.c: Include config.h from . instead of ../common.
5097 * Make-common.in: Remove. It's no longer necessary.

5169
5170 * run.c (main): Removed SH specific comments, so source is
