Subject: [PATCH 4/6] Fix macro problem with gai_strerror on Windows.

Commit 5579388d was confused about why gai_strerror() didn't work on
Windows, and had to be redirected with a macro to gai_strerrorA().  It
turns out that we explicitly undefined Windows' own macro for that
somewhere else.  Oops.  Get rid of all that, so now we can use
gai_sterror() directly using declarations from the system headers.
