+ * 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.
