2165         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
2166         into here.  Makes insertion into makefiles easier.  Also, change
2167         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
2168         targ-map.o, and run are built.  They are now built in the
2169         individual simulator directories, taking sources from ../common as
2170         necessary.  This replaces the merging of libcommon.a into
2171         linsim.a, which was problematic for the WinGDB build process.
2172         * run.c:  Include config.h from . instead of ../common.

2204         Parse program name from argv[0] and use in error messages.
2205         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
2206         Add support for incomplete h8/300 termination indicators.
2207         (usage): Make more verbose.
2208         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
