5905         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5906         targ-map.o, and run are built.  They are now built in the
5907         individual simulator directories, taking sources from ../common as
5908         necessary.  This replaces the merging of libcommon.a into
5909         linsim.a, which was problematic for the WinGDB build process.

5942         Parse program name from argv[0] and use in error messages.
5943         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
5944         Add support for incomplete h8/300 termination indicators.
5945         (usage): Make more verbose.
5946         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
