This isn't in my man pages... in fact, little of the Sun stuff seems
to be.  I wish GNU would keep them as updated as they seem to do their
info stuff.  I just don't default to going there for information.

Anyway, I made an error in my scripting to test the various compiler
options, -mcpu=supersparc is definitely OK.  My bad.

I panicked for a few momoments, thinking all those hours of rebuilding
had the wrong options... :)
