This is true. I don't know of any modern OS without IPv6 support,
even Windows provides these structures ;)

If there is really a platform without sockaddr_in6, this should
be catched by configure (reverting to v4-only code, a little
tricky, yes).

As far as I know: All BSDs have v6, Linux has, HPUX, AIX, Solaris,
Windows (XP for sure, 2000 experimental, 9X/ME don't).
