Our ipv6 stuff is in cygwin/in6.h, which is included by cygwin/in.h,
which in turn is included by netinet/in.h.

We could fetch FreeBSDs netinet/ip6.h.  In contrast to Glibc's=20
netinet/ip6.h it does not include netinet/in.h but we could add
that.

Aaron, if you copy this file:

http://svnweb.freebsd.org/base/stable/10/sys/netinet/ip6.h?revision=3D25628=
1&view=3Dco

into /usr/include/netinet, and perhaps add this patch:

can you build socat with IPv6 support out of the box and it actually
works?
