I was interested to know how this compares with existing C libraries, so I "ported" the prime number example program to use GMP and GLib instead. It's not quite working yet (see the description) and I have to run now, but here's the code--I think it's nearly complete and would be interesting to benchmark once done. https://gist.github.com/jzwinck/5787359

Shoot, if I had known someone was going to do this I would have made the prime number program a bit more efficient. Since it looks like you've ported the algorithm exactly it shouldn't affect the result though. Let me know what the test reveals, I tried to write the fasted arbitrary precision algorithms I could.
