Thanks to Jason's recommendation, I was finally able to get a 64bit
Linux distro working on my Core2 machine so I have now been able to
benchmark MPIR in Linux and Vista 64bit on the same machine.
I have attached the miprbench and speed test results for both
operating systems. There is definitely a difference between the two.
Vista 64bit = MPIRbench result: 11985.85
Linus 64bit = MPIRbench result: 13172
Some of the speed timings are quite different, but the
mpn_mul_basecase more more similar than the rest.
