5471
5472Tue Feb 4 13:24:44 1997 Doug Evans <dje@canuck.cygnus.com>
5473
5474 * Makefile.in (libcommon.a): Delete.
5475 (callback.o,targ-map.o): Delete, moved to Make-common.in.
5476 (gentmap,targ-vals.h,targ-map.c): Likewise.

5501 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5502 targ-map.o, and run are built. They are now built in the
5503 individual simulator directories, taking sources from ../common as
5504 necessary. This replaces the merging of libcommon.a into
5505 linsim.a, which was problematic for the WinGDB build process.
5506 * run.c: Include config.h from . instead of ../common.
5507 * Make-common.in: Remove. It's no longer necessary.

5579
5580 * run.c (main): Removed SH specific comments, so source is
