/* Under IEEE 754, an architecture may determine tininess of
floating-point results either "before rounding" or "after
rounding", but must do so in the same way for all operations
returning binary results. Define TININESS_AFTER_ROUNDING to 1 for
"after rounding" architectures, 0 for "before rounding"
architectures. The test stdlib/tst-tininess will fail if the
definition is incorrect. */
