[PATCH 2/4] configure: Force --disable-input-thread for MinGW

[Jon Turney]

I don't think an input thread can ever be useful on Windows.

There is a pthread emulation, so having the thread itself isn't much of a
problem.

However, there is no device to wait on for Windows events, and even if we
were to replace select() with WFMO, Windows wants to send events for a
window to the thread which created that window.

So, force --disable-input-thread
