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

 396         Add support for incomplete h8/300 termination indicators.
