Hi all,
At first, I told a lie in one point,

We removed all the varargs functions from the IPv4 stack (#ifdef'ed
for FreeBSD), but preserved for the IPv6 stack. This is for our
inter-OS source code maintainancability. We share all the IPv6 code
among the *BSDs. Since we are developing the IPv6 stack actively now,
it is important for us to reduce the difference among several OSes.
Anyway, as we don't have any varargs input/output functions in FreeBSD
code any more, some of annoying warning messages have disappeared.

Please look into the attached patch for FreeBSD-current.
