Subject: [PATCH] configure: Force --disable-input-thread for MinGW
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, disable input thread by default for MinGW
v2:
Also add similar to meson.build
