As you may expect, I have every variation of Sun Studio from rev 8 through
12.1 on everything from 15 year old Sparc to quite modern systems in the
Blastwave build farm. I can tell you that I have long since given up on
using these compilers for GMP but I do use them for everything else.
Almost everything. The GCC 4.3.4 compiler ( also avail from Blastwave )
works flawlessly on every platform and I get excellent results.

I just need to calrify, because perhaps I need to go back to the Studio
compilers, do you want me to try using the Studio compilers for the latest
GMP? I think I tried it once or twice and I hit bugs in every case. If you
need someone to hammer the Studio compilers then I can give it a try.

Better yet, you can just send me your ssh key and I will get you set up in
the farm and you can do these things yourself at your leisure. :-)
