80b7b3a5
SG		 2091 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
2092 into here. Makes insertion into makefiles easier. Also, change
2093 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
2094 targ-map.o, and run are built. They are now built in the
2095 individual simulator directories, taking sources from ../common as
2096 necessary. This replaces the merging of libcommon.a into
2097 linsim.a, which was problematic for the WinGDB build process.
2098 * run.c: Include config.h from . instead of ../common.
2099 * Make-common.in: Remove. It's no longer necessary.
