I'll improve the patch, test it on some platforms, and then send an
updated version...

The libc implementation of getaddrinfoisn't covered by GPL.  It also
uses standard POSIX APIs like gethostbyname (but threaded versions),
though.  So I guess it can serve as inspiration for how to implement
some flags etc, but perhaps I shouldn't look too closely at it to
avoid infringing on the copyright.
