5477
5478Tue Feb 4 13:24:44 1997 Doug Evans <dje@canuck.cygnus.com>
5479
5480 * Makefile.in (libcommon.a): Delete.
5481 (callback.o,targ-map.o): Delete, moved to Make-common.in.
5482 (gentmap,targ-vals.h,targ-map.c): Likewise.

5507 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5508 targ-map.o, and run are built. They are now built in the
5509 individual simulator directories, taking sources from ../common as
5510 necessary. This replaces the merging of libcommon.a into
5511 linsim.a, which was problematic for the WinGDB build process.
5512 * run.c: Include config.h from . instead of ../common.
5513 * Make-common.in: Remove. It's no longer necessary.

5585
5586 * run.c (main): Removed SH specific comments, so source is
