3468         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in

3470         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
3471         targ-map.o, and run are built.  They are now built in the
3472         individual simulator directories, taking sources from ../common as
3473         necessary.  This replaces the merging of libcommon.a into
3474         linsim.a, which was problematic for the WinGDB build process.
3475         * run.c:  Include config.h from . instead of ../common.

3508         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
3509         Add support for incomplete h8/300 termination indicators.
3510         (usage): Make more verbose.
