Thanks to all who responded.  Based on the various feedback, it seem like 
for most (all?) people their box arrives with a recent enough GMP/MPFR or 
they already have to get a sufficiently recent copy from source and build it 
in-tree.

So upgrading GCC's requirements to gmp-4.2 and mpfr-2.3.1 should be 
minimally disruptive.  I'll prepare a patch for 4.5.
