3475         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
3476         into here.  Makes insertion into makefiles easier.  Also, change
3477         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
3478         targ-map.o, and run are built.  They are now built in the
3479         individual simulator directories, taking sources from ../common as
3480         necessary.  This replaces the merging of libcommon.a into
3481         linsim.a, which was problematic for the WinGDB build process.
3482         * run.c:  Include config.h from . instead of ../common.

3515         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
3516         Add support for incomplete h8/300 termination indicators.
3517         (usage): Make more verbose.
3518         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
