Attached is a combined revised patch that attempts to automate that part.
Doing this properly would require a configure-time test for
__int128, which is probably overkill (would affect all builds,
whereas this is just needed occasionally).

This patch also shrinks primes.h somewhat by having the target
compiler do more of the work.
