6260         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
6261         targ-map.o, and run are built.  They are now built in the
6262         individual simulator directories, taking sources from ../common as
6263         necessary.  This replaces the merging of libcommon.a into
6264         linsim.a, which was problematic for the WinGDB build process.
6265         * run.c:  Include config.h from . instead of ../common.

6297         Parse program name from argv[0] and use in error messages.
6298         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
6299         Add support for incomplete h8/300 termination indicators.
6300         (usage): Make more verbose.
6301         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
