That's the GCC version, the MPFR version should be something like 2.2.x or
2.3.0.

Hmmm. That's strange. Can you try the following program (if needed, use
-fno-range-check):
print *, transfer(4294967295_8, 0.0)
print '(z12)', transfer(real(z'FFFFFFFF'), 1)
print *, transfer(2143289344_8, 0.0)
print '(z12)', transfer(real(z'7FC00000'), 1)
print *, real(z'7FC00000')
END
In principle, I would expect: NaN, FFFFFFFF, NaN, 7FC00000, NaN
At least that's what I get on x86-64 with several compilers.
