-/* mpz_get_str (string, base, mp_src) -- Convert the multiple precision
-   number MP_SRC to a string STRING of base BASE.  If STRING is NULL
-   allocate space for the result.  In any case, return a pointer to the
-   result.  If STRING is not NULL, the caller must ensure enough space is
-   available to store the result.
