Some co-workers started investigating this today, and found a patch from
Red Hat which apparently was not shared with bug-gmp.  Even with the
patch gmp still fails 19 out of 21 of its tests, so i'm not sure the
patch accomplishes much.  We're still investigating the issue.  Anyway,
i have attached the patch (by Philipp Knirsch <pknirsch@redhat.de>).

For what it's worth: I just tried gmp-3.1.1-4.src.rpm from the Red Hat
"roswell" beta and it passes all tests.  As far as I can tell, there
are no ia64-specific patches other than the one you mentioned.

Thanks, I think the gcc register flags changed at some point.
