3432         (callback.o,targ-map.o): Delete, moved to Make-common.in.
3433         (gentmap,targ-vals.h,targ-map.c): Likewise.
3434         (run-autoconf): Delete.
3435         * aclocal.m4 (SIM_AC_OUTPUT): Redo creation of Makefile.

3454         * (distclean):  Remove targ-vals.def.
3455
3456         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in
3457         into here.  Makes insertion into makefiles easier.  Also, change
3458         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
3459         targ-map.o, and run are built.  They are now built in the
3460         individual simulator directories, taking sources from ../common as
3461         necessary.  This replaces the merging of libcommon.a into
3462         linsim.a, which was problematic for the WinGDB build process.
3463         * run.c:  Include config.h from . instead of ../common.
3464         * Make-common.in:  Remove.  It's no longer necessary.

3495         Parse program name from argv[0] and use in error messages.
3496         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
3497         Add support for incomplete h8/300 termination indicators.
3498         (usage): Make more verbose.
3499         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
