+/* 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.
