1048         into here.  Makes insertion into makefiles easier.  Also, change
1049         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
1050         targ-map.o, and run are built.  They are now built in the
1051         individual simulator directories, taking sources from ../common as
1052         necessary.  This replaces the merging of libcommon.a into
1053         linsim.a, which was problematic for the WinGDB build process.
1054         * run.c:  Include config.h from . instead of ../common.
1055         * Make-common.in:  Remove.  It's no longer necessary.
