Factoring GP+10

Dario Alpern is collecting factors of googolplex+10 (GP+10 for short). In fact he's collecting factors of 10^10^100+x for x in 0..999. David Broadhurst wrote a pari/gp script to find factors, I've translated it to C and optimised it somewhat. Source is available, as are windows exes and GMP dlls to build from scratch. This page is thrown together in 2 minutes, can you tell?

Note - the windows executable is unable to go beyond k=48000, as it will overflow. The source is fixed though.
