This problem shipped in 2009.11 also -
Fails even if mpfr is put into the GCC tree -

Looks like it might be tied in with the logic of building Fortran -
(GCC once only used mpfr on the Fortran builds).
Haven't had time for further testing myself.

There is what might be a related bug report already posted.
