It is clear to me that we cannot entirely rely on the availability of IPv6-mapped IPv4 addresses. Getting the IPv6-enabled sources to compile on systems without sockaddr_in6 or getaddrinfo() is sort of nasty, but should be possible. For example, we could extend the configure script to test this and provide some drop-in replacements in case these structures/call are missing on the system. Are there some reference platforms which are really old, but need to be supported?
