5157         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in

5159         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5160         targ-map.o, and run are built.  They are now built in the
5161         individual simulator directories, taking sources from ../common as
5162         necessary.  This replaces the merging of libcommon.a into
5163         linsim.a, which was problematic for the WinGDB build process.
5164         * run.c:  Include config.h from . instead of ../common.

5196         Parse program name from argv[0] and use in error messages.
5197         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
5198         Add support for incomplete h8/300 termination indicators.
5199         (usage): Make more verbose.
5200         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
