* Quad arithmetic.
*
* This library makes the following assumptions:
*
* - The type long long (aka quad_t) exists.
*
* - A quad variable is exactly twice as long as `int'.
*
* - The machine's arithmetic is two's complement.
*
* This library can provide 128-bit arithmetic on a machine with 128-bit
* quads and 64-bit ints, for instance, or 96-bit arithmetic on machines
* with 48-bit ints.
