Subject: [PATCH] configure: Check for getaddrinfo in ws2tcpip.h, too
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This function is only available in the headers if unconditionally
targeting a version >= XP. It is not strictly necessary, since we
try loading these functions dynamically at runtime on windows in
the fallback, but this makes things a bit faster and more
straightforward.

On mingw32, this function isn't visible by default, while it is
on mingw64 (on both 32 and 64 bit).
