mpz_primorial_ui( ) is a great function.  Why not return the actual
number of primes that go into that calculation?  The argument n is an
unsigned long int, and the return argument could be as well.  It is
often valuable to know that number, and mpz_primorial_ui(...) has done
all of the heavy lifting.
