The GWNUM library can be used on numbers (or factors of numbers) of the form k*b^n+c. And, from the little testing I have been able to perform, it seems the larger the input number, the greater the speed-up you can get from GWNUM in stage 1.
Where is the source for GWNUM? I would certainly like the speedup! And I'm not afraid of compiling programs.

This assumes it works under Linux.
