/* Version 2.2.0 of MPFR had bugs in pow underflow/overflow. This
test checks to see if that buggy version was installed. The
problem is NOT fixed with the version 2.2.0 "cumulative patch".
However it is fixed in version 2.2.1 and presumably later MPFR
versions.
Origin: Kaveh R. Ghazi 12/17/2006. */
