1538         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
1539         targ-map.o, and run are built.  They are now built in the
1540         individual simulator directories, taking sources from ../common as
1541         necessary.  This replaces the merging of libcommon.a into
1542         linsim.a, which was problematic for the WinGDB build process.
1543         * run.c:  Include config.h from . instead of ../common.

1575         Parse program name from argv[0] and use in error messages.
1576         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
1577         Add support for incomplete h8/300 termination indicators.
1578         (usage): Make more verbose.
1579         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
