5046 * (distclean): Remove targ-vals.def.
5047
5048 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
5049 into here. Makes insertion into makefiles easier. Also, change
5050 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5051 targ-map.o, and run are built. They are now built in the
5052 individual simulator directories, taking sources from ../common as
5053 necessary. This replaces the merging of libcommon.a into
5054 linsim.a, which was problematic for the WinGDB build process.
5055 * run.c: Include config.h from . instead of ../common.
5056 * Make-common.in: Remove. It's no longer necessary.
5057
