5095         (callback.o,targ-map.o): Delete, moved to Make-common.in.
5096         (gentmap,targ-vals.h,targ-map.c): Likewise.
5097         (run-autoconf): Delete.
5098         * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.
5099         (common makefile fragment): Moved back into ...

5116         * aclocal.m4:  Remove Make-common.in from dependencies.
5117         * (distclean):  Remove targ-vals.def.
5118
5119         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
5120         into here.  Makes insertion into makefiles easier.  Also, change
5121         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5122         targ-map.o, and run are built.  They are now built in the
5123         individual simulator directories, taking sources from ../common as
5124         necessary.  This replaces the merging of libcommon.a into
5125         linsim.a, which was problematic for the WinGDB build process.
5126         * run.c:  Include config.h from . instead of ../common.
5127         * Make-common.in:  Remove.  It's no longer necessary.

5158         Parse program name from argv[0] and use in error messages.
5159         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
5160         Add support for incomplete h8/300 termination indicators.
5161         (usage): Make more verbose.
5162         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
