7206         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in

7208         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
7209         targ-map.o, and run are built.  They are now built in the
7210         individual simulator directories, taking sources from ../common as
7211         necessary.  This replaces the merging of libcommon.a into
7212         linsim.a, which was problematic for the WinGDB build process.
7213         * run.c:  Include config.h from . instead of ../common.

7246         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
7247         Add support for incomplete h8/300 termination indicators.
7248         (usage): Make more verbose.
7249         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
