5768
5769         * callback.c: If HAVE_CONFIG_H is defined, include config.h from
5770         autoconf.  If HAVE_UNISTD_H is defined, include unistd.h to get
5771         appropriate definitions of read, write, etc.  Add prototype for
5772         system.

5777         (callback.o,targ-map.o): Delete, moved to Make-common.in.
5778         (gentmap,targ-vals.h,targ-map.c): Likewise.
5779         (run-autoconf): Delete.
5780         * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.
5781         (common makefile fragment): Moved back into ...
5782         * Make-common.in: Resurrect.

5797
5798         * aclocal.m4:  Remove Make-common.in from dependencies.
5799         * (distclean):  Remove targ-vals.def.
5800
5801         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
5802         into here.  Makes insertion into makefiles easier.  Also, change
5803         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5804         targ-map.o, and run are built.  They are now built in the
5805         individual simulator directories, taking sources from ../common as
5806         necessary.  This replaces the merging of libcommon.a into
5807         linsim.a, which was problematic for the WinGDB build process.
5808         * run.c:  Include config.h from . instead of ../common.
5809         * Make-common.in:  Remove.  It's no longer necessary.

5840         Parse program name from argv[0] and use in error messages.
5841         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
5842         Add support for incomplete h8/300 termination indicators.
5843         (usage): Make more verbose.
5844         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.

5881
5882         * run.c (main): Removed SH specific comments, so source is
