Don't EOL me ;-) One of my machines (the one I'm typing this on,
actually) still happily runs XP, and probably will for some time to
come.

It's up to us to decide. Emacs, for example, still supports Windows
98, per an explicit request from RMS, based on the large number of
users of those systems in the 3rd World.

Why can't we test at run time if getaddrinfo is available, and use it
if it is, else use the old code? This will work on Windows, and is
much simpler than the gnulib rigmarole.
