Well *everything* builds fine with GCC 4.3.4 and binutils on Sparc and
i386/x86_64 in both 32 and 64 bit modes.

On x86 platforms I am seeing wonderful speed increase from the older libs
that I had built last year. Really wonderful.  Sparc shows no real
measurable change at all.

When I have some more conclusive data I will share it and/or blog about it.

Really wonderful work in gmp 5.0.1.
