I'm afraid your Berkeley systems are out-of-date. Since the days of BSD 4.3
the default IP broadcast address is indeed hostpart = all ones, thereby
correcting the BSD 4.2 anomaly of using all zeros, which was not according
to the recommendation in RFC919.
So rather than condemning Apple's AUX on his point, it should be praised,
for keeping up-to-date with current IP broadcast standards.
