-m64, if whatever version of GCC you're using already supports this
option.  But note that, even in GCC 3.0.x, such option is only
partially supported, and there are situations in which it is known to
fail.  Using -mcpu=ultrasparc instead generally gets you most of the
benefit without running into the known problems.  If you really want
64-bit code, better get a GCC 3.1 development snapshot, or wait for
the final release.
