4676
4677Tue Feb 4 13:24:44 1997 Doug Evans <dje@canuck.cygnus.com>
4678
4679 * Makefile.in (libcommon.a): Delete.
4680 (callback.o,targ-map.o): Delete, moved to Make-common.in.

4706 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
4707 targ-map.o, and run are built. They are now built in the
4708 individual simulator directories, taking sources from ../common as
4709 necessary. This replaces the merging of libcommon.a into
4710 linsim.a, which was problematic for the WinGDB build process.
4711 * run.c: Include config.h from . instead of ../common.
4712 * Make-common.in: Remove. It's no longer necessary.

4784
4785 * run.c (main): Removed SH specific comments, so source is
