Alpha VM on Solaris UltraSPARC?

[Brian Rice]

UltraSPARC processors have 64-bit words. I recall that builds on 64-bit 
systems have issues currently (judging from a G5 build and an AMD-64 
build others have attempted). Neither Lee nor I have quick access to 
one, so there is a gap here in porting/debugging. If you can work on it 
or if someone can provide access so that we can work on it, we'd 
probably able to resolve the issues there.
