  22   * The original fdlibm code used statements like:
  23   *     n0 = ((*(int*)&one)>>29)^1;             * index of high word *
  24   *     ix0 = *(n0+(int*)&x);                   * high word of x *
  25   *     ix1 = *((1-n0)+(int*)&x);               * low word of x *
  26   * to dig two 32 bit words out of the 64 bit IEEE floating point
  27   * value.  That is non-ANSI, and, moreover, the gcc instruction
  28   * scheduler gets it wrong.  We instead use the following macros.
