2182         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
2183         targ-map.o, and run are built.  They are now built in the
2184         individual simulator directories, taking sources from ../common as
2185         necessary.  This replaces the merging of libcommon.a into
2186         linsim.a, which was problematic for the WinGDB build process.
2187         * run.c:  Include config.h from . instead of ../common.

2219         Parse program name from argv[0] and use in error messages.
2220         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
2221         Add support for incomplete h8/300 termination indicators.
2222         (usage): Make more verbose.
2223         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
