Yep, there are a few problems like the one you reported.  It's no
problem if you tell GCC to *tune* the optimizer for ultrasparc,
(-mtune=ultrasparc), but don't tell it to use ultrasparc-specific
instructions (-mcpu=ultrasparc), otherwise it will fail as reported.

All of them do, it's just that support for ultrasparc-specific
instructions was not fully implemented by release 2.95, and I'm not
sure they are in the latest snapshots.
