4847         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
4848         targ-map.o, and run are built.  They are now built in the
4849         individual simulator directories, taking sources from ../common as
4850         necessary.  This replaces the merging of libcommon.a into
4851         linsim.a, which was problematic for the WinGDB build process.

4884         Parse program name from argv[0] and use in error messages.
4885         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
4886         Add support for incomplete h8/300 termination indicators.
4887         (usage): Make more verbose.
4888         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
