1857         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
1858         targ-map.o, and run are built.  They are now built in the
1859         individual simulator directories, taking sources from ../common as
1860         necessary.  This replaces the merging of libcommon.a into
1861         linsim.a, which was problematic for the WinGDB build process.
1862         * run.c:  Include config.h from . instead of ../common.

1894         Parse program name from argv[0] and use in error messages.
1895         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
1896         Add support for incomplete h8/300 termination indicators.
1897         (usage): Make more verbose.
1898         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
