Clearly the getifaddrs code looks nicer. How can we distinguish the
SIOCGIFCONF implementations that have wrinkles from those that don't?
Is there some autoconf macro?
Something to keep in mind -- my getifaddrs(3) manpage says that on BSD
it can return addresses that have ifa_addr set to NULL, which your code
doesn't seem to check.
