I think that depends on how much remaining use there is of these
functions. Saying that the entire behavior is "undefined" is too loose
(but only because I remember the original implementation of #pragma in
the GNU cpp). It would better to say that the functions use an
unspecified value for the address mask.
BTW, the current man pages make no mention of the "de-facto obsolete"
status of those three functions -- we should probably declare
inet_lnaof(), inet_netof(), and inet_makeaddr() Obsolete as part of this
case.
