        * syscall.h: Added SYS_times, SYS_gettimeofday, SYS_link values.
        * mn10300/times.c: Renamed "times" to "_times" so that it can be
        referenced by newlib.
        * mn10300/cygmon.c: New file.
        * mn10300/crt0_redboot.S: Ditto.
        * mn10300/crt0_cygmon.S: Ditto.
        * mn10300/Makefile.in: Added RedBoot and Cygmon support.
        * mn10300/configure.in: Changed to allow for future
        evaluation boards to be added.
        * mn10300/configure: Regenerated.
