5209         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5210         targ-map.o, and run are built.  They are now built in the
5211         individual simulator directories, taking sources from ../common as
5212         necessary.  This replaces the merging of libcommon.a into
5213         linsim.a, which was problematic for the WinGDB build process.

5246         Parse program name from argv[0] and use in error messages.
5247         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
5248         Add support for incomplete h8/300 termination indicators.
5249         (usage): Make more verbose.
5250         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
