1757
1758         * callback.c: If HAVE_CONFIG_H is defined, include config.h from
1759         autoconf.  If HAVE_UNISTD_H is defined, include unistd.h to get
1760         appropriate definitions of read, write, etc.  Add prototype for
1761         system.

1766         (callback.o,targ-map.o): Delete, moved to Make-common.in.
1767         (gentmap,targ-vals.h,targ-map.c): Likewise.
1768         (run-autoconf): Delete.
1769         * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.
1770         (common makefile fragment): Moved back into ...
1771         * Make-common.in: Resurrect.

1786
1787         * aclocal.m4:  Remove Make-common.in from dependencies.
1788         * (distclean):  Remove targ-vals.def.
1789
1790         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
1791         into here.  Makes insertion into makefiles easier.  Also, change
1792         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
1793         targ-map.o, and run are built.  They are now built in the
1794         individual simulator directories, taking sources from ../common as
1795         necessary.  This replaces the merging of libcommon.a into
1796         linsim.a, which was problematic for the WinGDB build process.
1797         * run.c:  Include config.h from . instead of ../common.
1798         * Make-common.in:  Remove.  It's no longer necessary.

1829         Parse program name from argv[0] and use in error messages.
1830         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
1831         Add support for incomplete h8/300 termination indicators.
1832         (usage): Make more verbose.
1833         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.

1870
1871         * run.c (main): Removed SH specific comments, so source is
1872         generic. Also updated to only load relevant sections. Moved
1873         sim_open() to after callback attach (to match GDB).
