I think we do use the buggy features of MPFR 2.2.0 in GCC 4.2, but... just
in fortran, not the whole compiler.
However my patch is unnecessary in 4.2, because we already warn there when
MPFR is less than version 2.2.1. I patched that branch some time ago
because the MPFR check in 4.2 is only ever a warning, it never hard errors
unless you explicitly request fortran and don't have *any* version of
mpfr.
(I'm sure someone will correct me if I'm wrong on either count.)
