6248         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
6249         targ-map.o, and run are built.  They are now built in the
6250         individual simulator directories, taking sources from ../common as
6251         necessary.  This replaces the merging of libcommon.a into
6252         linsim.a, which was problematic for the WinGDB build process.
6253         * run.c:  Include config.h from . instead of ../common.

6285         Parse program name from argv[0] and use in error messages.
6286         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
6287         Add support for incomplete h8/300 termination indicators.
6288         (usage): Make more verbose.
6289         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
