7148         (callback.o,targ-map.o): Delete, moved to Make-common.in.
7149         (gentmap,targ-vals.h,targ-map.c): Likewise.
7150         (run-autoconf): Delete.
7151         * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.
7152         (common makefile fragment): Moved back into ...

7170         * (distclean):  Remove targ-vals.def.
7171
7172         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
7173         into here.  Makes insertion into makefiles easier.  Also, change
7174         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
7175         targ-map.o, and run are built.  They are now built in the
7176         individual simulator directories, taking sources from ../common as
7177         necessary.  This replaces the merging of libcommon.a into
7178         linsim.a, which was problematic for the WinGDB build process.
7179         * run.c:  Include config.h from . instead of ../common.

7211         Parse program name from argv[0] and use in error messages.
7212         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
7213         Add support for incomplete h8/300 termination indicators.
7214         (usage): Make more verbose.
7215         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
