SG		 3647 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
3648 into here. Makes insertion into makefiles easier. Also, change
3649 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
3650 targ-map.o, and run are built. They are now built in the
3651 individual simulator directories, taking sources from ../common as
3652 necessary. This replaces the merging of libcommon.a into
3653 linsim.a, which was problematic for the WinGDB build process.
3654 * run.c: Include config.h from . instead of ../common.
3655 * Make-common.in: Remove. It's no longer necessary.
