/* Unlike previous versions of this code, uint32 need not be exactly
32 bits, merely 32 bits or more. Choosing a data type which is 32
bits instead of 64 is not important; speed is considerably more
important. ANSI guarantees that "unsigned long" will be big enough,
and always using it seems to have few disadvantages. */
