getaddrinfo() is part of the IPv6 Basic Sockets API (see RFC 3493). So,
by definition, any platform which lacks that function cannot really be
said to support IPv6.

If OS400 lacks getaddrinfo() then, harsh as it might sound, I think the
best option is to provide an emulation for that function in some support
library. It sounds like libcurl already requires some wrapper
assistance to run properly on this platform for character-set reasons,
so this shouldn't be too much of a hardship.
