3466         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in

3468         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
3469         targ-map.o, and run are built.  They are now built in the
3470         individual simulator directories, taking sources from ../common as
3471         necessary.  This replaces the merging of libcommon.a into
3472         linsim.a, which was problematic for the WinGDB build process.
3473         * run.c:  Include config.h from . instead of ../common.

3506         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
3507         Add support for incomplete h8/300 termination indicators.
3508         (usage): Make more verbose.
