4790         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
4791         into here.  Makes insertion into makefiles easier.  Also, change
4792         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
4793         targ-map.o, and run are built.  They are now built in the
4794         individual simulator directories, taking sources from ../common as
4795         necessary.  This replaces the merging of libcommon.a into
4796         linsim.a, which was problematic for the WinGDB build process.
4797         * run.c:  Include config.h from . instead of ../common.

4830         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
4831         Add support for incomplete h8/300 termination indicators.
4832         (usage): Make more verbose.
4833         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
