which basically says the Xcode C compiler won't compile gmp properly.

What I want to know is,

(a) Is that caution out of date?

(b) If not, what do I have to do to work around the problem?

As far as I understand, you should install gcc from upstream source
use it to build gmp, instead of using xcode gcc.

Really?  I build gmp without problems on Mac OS X, both 10.4.11 and
10.5.2.  I am using the gcc supplied with Xcode 2.5 (build 5370) in
10.4  and 3.0 (build 5465) in 10.5.

In addition, gmp builds with "native" gcc in Sage (<http://
www.sagemath.org>) on these systems.  The Sage build does apply a
couple of patches (Mac OS X 10.5 and some versions of Linux, and for
some processors), but when I build gmp stand-alone, I just
"configure" and "make".

Did you run make check ?

Replying to both you and to Kurt: yes, for my stand-alone builds. All tests passed.

If this comes as a surprise, I will re-run the build to make sure I'm not remembering how it used to be...
