5861         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
5862         into here.  Makes insertion into makefiles easier.  Also, change
5863         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5864         targ-map.o, and run are built.  They are now built in the
5865         individual simulator directories, taking sources from ../common as
5866         necessary.  This replaces the merging of libcommon.a into
5867         linsim.a, which was problematic for the WinGDB build process.
5868         * run.c:  Include config.h from . instead of ../common.

5901         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
5902         Add support for incomplete h8/300 termination indicators.
5903         (usage): Make more verbose.
