 384         (callback.o,targ-map.o): Delete, moved to Make-common.in.
 385         (gentmap,targ-vals.h,targ-map.c): Likewise.
 386         (run-autoconf): Delete.
 387         * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.
 388         (common makefile fragment): Moved back into ...

 404
 405         * aclocal.m4:  Remove Make-common.in from dependencies.
 406         * (distclean):  Remove targ-vals.def.
 407
 408         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
 409         into here.  Makes insertion into makefiles easier.  Also, change
 410         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
 411         targ-map.o, and run are built.  They are now built in the
 412         individual simulator directories, taking sources from ../common as
 413         necessary.  This replaces the merging of libcommon.a into
 414         linsim.a, which was problematic for the WinGDB build process.
 415         * run.c:  Include config.h from . instead of ../common.
 416         * Make-common.in:  Remove.  It's no longer necessary.

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