6458         * sim-bits.h, sim-bits.c: Clean up conditionally compiled #if

6477         not generally applicable.
6478

6480
6481         * sim-bits.c, sim-bits-n.h (new): Split sim-bits.c into two parts

6557         * aclocal.m4 (SIM_AC_COMMON):  Move contents of Make-common.in

6559         the way that callback.o, gentmap, targ-vals.h, targ-map.c,
6560         targ-map.o, and run are built.  They are now built in the
6561         individual simulator directories, taking sources from ../common as
6562         necessary.  This replaces the merging of libcommon.a into
6563         linsim.a, which was problematic for the WinGDB build process.
6564         * run.c:  Include config.h from . instead of ../common.

6596         Parse program name from argv[0] and use in error messages.
6597         Pass sim_args to sim_open.  Pass prog_args to sim_create_inferior.
6598         Add support for incomplete h8/300 termination indicators.
6599         (usage): Make more verbose.
6600         * aclocal.m4,config.in,tconfig.in,configure.in,configure: New files.
