    ANSI/ISO C defines time_t as a signed arithmetic type, so
    such a change would break correct code.

    Note that the use of types not listed in the standard
    as the base type for time_t will also break correct code.
    This includes _long _long.

    Personally, I'd wait for the new ISO C's "long long" type
    and use that as the base type of time_t. This would be 64
    bits on a 32 bit architecture.

    Fixing the problem now requires increasing the size of "long"
    where it is currently 32 bits. This probably isn't a good idea.
