[ squint... ] They define IPV6_V6ONLY and AF_INET6 but not
IPPROTO_IPV6? That's pretty bizarre. You might want to hunt around in
the system header files for those symbols and see if there's some
feature macro or something we need to set to get IPPROTO_IPV6 to be
defined. Or maybe it's in some other header file that we're not
including.
