programs (like rshd or rlogind).
bindresvport() and bindresvport_sa() exhibits exactly the same functionality,
with different function prototype (sockaddr_in * and sockaddr *).
The behavior and prototype was discussed and agreed among shin@kame.net
(who is doing freebsd-current kame merge), deraadt@openbsd.org, and
Jean-Luc.Richier@imag.fr (INRIA IPv6/IPv6 RPC support). so it will be
portable across *bsd.
