No, that isn't the point either.

The point is that we currently check winsock2 headers even if configure has
determined that we don't have winsock2 on the machine. Later in the build
process we only include winsock2 headers if we really have winsock2.

For that very reason there are #if HAVE_WINSOCK2_H conditions in various
configure checks. Only for the headers, such a check is missing.

And, BTW, besides that the current behaviour clearly is a bug, it would be
nice if we could support more than just the very recent release of whatever.
