There will be a compatibility problem if a module assumes functionality
of full GMP that mini-gmp does not provide, e.g., NAILS != 0. The full
list of functionality missing in mini-gmp is documented in the
gmp/mini-gmp/README. It's a short list. It would probably help to
mention this issue in our module documentation.
Also, the gmp.h and mini-gmp.h ABIs are incompatible on a few old Cray
machines. I don't think we need to worry about this nowadays.
