Sounds a lot like PR39867 and PR40747 are hitting you. Can you grab those fixes, apply them to your 4.4.0, rebuild it, and test mpfr again? Or get the 4.4.1-RC and test that instead. I just finished building 4.3.4 and 4.4.0 on USIIIi/Solaris 9, and they built gmp-4.2.4 and mpfr-2.4.1 fine, with both passing make check. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=40757
