4834         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
4835         targ-map.o, and run are built.  They are now built in the
4836         individual simulator directories, taking sources from ../common as
4837         necessary.  This replaces the merging of libcommon.a into
4838         linsim.a, which was problematic for the WinGDB build process.

4872         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
4873         Add support for incomplete h8/300 termination indicators.
4874         (usage): Make more verbose.
4875         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
