Although you can input an arbitrarily large integer, the limit of what
the program can do in reasonable time is about 100 decimal digits for a
randomly chosen integer.

Well, the program has more than 10 source files and probably requires some
number theory know-how. I know that Paul Zimmermann is open to collaboration
with the GNU project (he's a contributor of GNU gmp, after all). It's up to
you to work it out with him.
