5063
5064Tue Feb 4 13:24:44 1997 Doug Evans <dje@canuck.cygnus.com>
5065
5066 * Makefile.in (libcommon.a): Delete.
5067 (callback.o,targ-map.o): Delete, moved to Make-common.in.
5068 (gentmap,targ-vals.h,targ-map.c): Likewise.

5093 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5094 targ-map.o, and run are built. They are now built in the
5095 individual simulator directories, taking sources from ../common as
5096 necessary. This replaces the merging of libcommon.a into
5097 linsim.a, which was problematic for the WinGDB build process.
5098 * run.c: Include config.h from . instead of ../common.
5099 * Make-common.in: Remove. It's no longer necessary.
