  24    floating-point results either "before rounding" or "after
  25    rounding", but must do so in the same way for all operations
  26    returning binary results.  Define TININESS_AFTER_ROUNDING to 1 for
  27    "after rounding" architectures, 0 for "before rounding"
  28    architectures.  The test stdlib/tst-tininess will fail if the
