// GNULLIVER_TEST is the magic number we use to determine byte swapping in
// a 64-bit word. It assumes IEEE 754 floating point, and encodes to
// hexadecimal 0x40302010 00000000 on a Big-endian (network order) machine.
// The mantissa is large enough that it might work on a non-IEEE 754 compatible
// machine just by coincidence, but no guarantees.
//
// gnulliver currently assumes that if we swap 32-bit values in a 64-bit word,
// then we also swap 64-bit values in a 128-bit word (long double), which is
// true if the machine is Little-endian. If this does not hold true on a
// particular platform, let me know and I'll modify the code.
