3408
3409         * callback.c: If HAVE_CONFIG_H is defined, include config.h from
3410         autoconf.  If HAVE_UNISTD_H is defined, include unistd.h to get
3411         appropriate definitions of read, write, etc.  Add prototype for
3412         system.

3417         (callback.o,targ-map.o): Delete, moved to Make-common.in.
3418         (gentmap,targ-vals.h,targ-map.c): Likewise.
3419         (run-autoconf): Delete.
3420         * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.
3421         (common makefile fragment): Moved back into ...
3422         * Make-common.in: Resurrect.

3437
3438         * aclocal.m4:  Remove Make-common.in from dependencies.
3439         * (distclean):  Remove targ-vals.def.
3440
3441         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
3442         into here.  Makes insertion into makefiles easier.  Also, change
3443         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
3444         targ-map.o, and run are built.  They are now built in the
3445         individual simulator directories, taking sources from ../common as
3446         necessary.  This replaces the merging of libcommon.a into
3447         linsim.a, which was problematic for the WinGDB build process.
3448         * run.c:  Include config.h from . instead of ../common.
3449         * Make-common.in:  Remove.  It's no longer necessary.

3480         Parse program name from argv[0] and use in error messages.
3481         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
3482         Add support for incomplete h8/300 termination indicators.
3483         (usage): Make more verbose.
3484         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.

3521
3522         * run.c (main): Removed SH specific comments, so source is
3523         generic. Also updated to only load relevant sections. Moved
