Errr, well,
I have installed the version from macports on my macbook pro, and it works fine.
No new regressions in the gcc testsuite since the GMP patches.

Uh, what?

In this case, I have no idea what problems you are experiencing, as
the version of GMP/MPFR required works fine on macbook pro, AFAICT.

It's actually about time we got to using GMP in the middle end, and I
don't believe reverting a patch because some non-primary platforms
have a few pains here and there initially is the best course of
action.

Also, although I experience no regressions, i'll point out that there
is no automated tested for macintel darwin that posts to
gcc-testresults, which does not bode well for something you would like
to be a primary platform.
