[PATCH]: Require MPFR 2.2.1

[Kaveh R. GHAZI]

This patch updates configure to require MPFR 2.2.1 as promised here:
http://gcc.gnu.org/ml/gcc/2006-12/msg00054.html

Tested on sparc-sun-solaris2.10 using mpfr-2.2.1, mpfr-2.2.0 and an older
mpfr included with gmp-4.1.4.  Only 2.2.1 passed (as expected).

I'd like to give everyone enough time to update their personal
installations and regression testers before installing this.  Does one
week sound okay?  If there are no objections, that's what I'd like to do.

Okay for mainline?

		Thanks,
		--Kaveh
