+/* mpz_init_set_str(string, base) -- Convert the \0-terminated string STRING in
+   base BASE to a multiple precision integer.  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.
