Subject: [PATCH] Check for getaddrinfo in the winsock headers.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This makes us link directly to getaddrinfo if it is available, making
binaries incompatible with anything prior to windows XP. If compatibility
is desired, compile with --target-os=mingw32-prexp.

Patch by Martin Storsjö <martin at martin dot st>.
