Here's the old message I recalled:
http://gcc.gnu.org/ml/gcc/2006-10/msg00640.html
it says you have to configure GMP with --host=none-apple-darwin
I assume you should do the same configure flag with MPFR.
What version of GMP are you using and where did you get it?
You may have a buggy GMP or MPFR, not sure which.
