    Hrmp. Because time_t is probably signed, technically this can cause
    `undefined behavior' if the range of `long' is more than the range of
    `time_t' (e.g. on alpha). *sigh*

    All I really want to do is correct a parsing bug and at the same time
    eliminate a warning so that I can set WARNS?=1 in libc before the code
    freeze.

    Cheers,
