It currently test to see if errno == -EINVAL and whether the endptr is '\0'. That's not correct however. What we really want it to do is check to see if any error occurred by setting errno to 0 before the conversion. If one did, then try to treat the value as a name. Also fix a bogus compiler warning about cruid being uninitialized.
