      You might want to check the newest Xcode 3.1.2 release if you
  have Leopard installed on your test machine. The -fno-pic issue at
  -m32 doesn't appear to exist under that Xcode release. I don't know
  if that is true for Xcode 2.5 under Tiger (it has been ages since
  I had a machine running that).

I prefer to stick to the tools I have, and let users test with more
recent versions of Apple's bugtools.

(It is actually good if we can make GMP build with a range of Xcode
releases.)
