  22   *     ix0 = *(n0+(int*)&x);                   * high word of x *
  23   *     ix1 = *((1-n0)+(int*)&x);               * low word of x *
  24   * to dig two 32 bit words out of the 64 bit IEEE floating point
  25   * value.  That is non-ANSI, and, moreover, the gcc instruction
  26   * scheduler gets it wrong.  We instead use the following macros.
  27   * Unlike the original code, we determine the endianness at compile
  28   * time, not at run time; I don't see much benefit to selecting
  29   * endianness at run time.
