49 (arch, cpu, decode, cpu-decode, defs, desc): Place the name of the

5052 autoconf. If HAVE_UNISTD_H is defined, include unistd.h to get
5053 appropriate definitions of read, write, etc. Add prototype for
5054 system.
5055
5056Tue Feb 4 13:24:44 1997 Doug Evans <dje@canuck.cygnus.com>
5057
5058 * Makefile.in (libcommon.a): Delete.
5059 (callback.o,targ-map.o): Delete, moved to Make-common.in.
5060 (gentmap,targ-vals.h,targ-map.c): Likewise.

5076 comments and single quotes. Fixes a problem found on hpux.
5077

5085 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5086 targ-map.o, and run are built. They are now built in the
5087 individual simulator directories, taking sources from ../common as
5088 necessary. This replaces the merging of libcommon.a into
5089 linsim.a, which was problematic for the WinGDB build process.
5090 * run.c: Include config.h from . instead of ../common.
5091 * Make-common.in: Remove. It's no longer necessary.

5163
5164 * run.c (main): Removed SH specific comments, so source is
