5783
5784         * callback.c: If HAVE_CONFIG_H is defined, include config.h from
5785         autoconf.  If HAVE_UNISTD_H is defined, include unistd.h to get
5786         appropriate definitions of read, write, etc.  Add prototype for
5787         system.

5792         (callback.o,targ-map.o): Delete, moved to Make-common.in.
5793         (gentmap,targ-vals.h,targ-map.c): Likewise.
5794         (run-autoconf): Delete.
5795         * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.
5796         (common makefile fragment): Moved back into ...

5812
5813         * aclocal.m4:  Remove Make-common.in from dependencies.
5814         * (distclean):  Remove targ-vals.def.
5815
5816         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
5817         into here.  Makes insertion into makefiles easier.  Also, change
5818         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5819         targ-map.o, and run are built.  They are now built in the
5820         individual simulator directories, taking sources from ../common as
5821         necessary.  This replaces the merging of libcommon.a into
5822         linsim.a, which was problematic for the WinGDB build process.
5823         * run.c:  Include config.h from . instead of ../common.
5824         * Make-common.in:  Remove.  It's no longer necessary.

5855         Parse program name from argv[0] and use in error messages.
5856         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
5857         Add support for incomplete h8/300 termination indicators.
5858         (usage): Make more verbose.
5859         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
