-/* mpz_set_str(mp_dest, string, base) -- Convert the \0-terminated
-   string STRING in base BASE to multiple precision integer in
-   MP_DEST.  Allow white space in the string.  If BASE == 0 determine
-   the base in the C standard way, i.e.  0xhh...h means base 16,
-   0oo...o means base 8, otherwise assume base 10.
