4684
4685Tue Feb 4 13:24:44 1997 Doug Evans <dje@canuck.cygnus.com>
4686
4687 * Makefile.in (libcommon.a): Delete.
4688 (callback.o,targ-map.o): Delete, moved to Make-common.in.
4689 (gentmap,targ-vals.h,targ-map.c): Likewise.

4714 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
4715 targ-map.o, and run are built. They are now built in the
4716 individual simulator directories, taking sources from ../common as
4717 necessary. This replaces the merging of libcommon.a into
4718 linsim.a, which was problematic for the WinGDB build process.
4719 * run.c: Include config.h from . instead of ../common.
4720 * Make-common.in: Remove. It's no longer necessary.
