You will need to do this first, otherwise it won't be built for OS_WIN &&
USE_AURA

I think the above code is right even on WIN + AURA (I was going to use the raw X
event-type directly like the windows message type here too, but didn't want to
replicate the code for XI and XI2).

[Ben Goodger (Google), 2011/11/01 16:30:14]

OK, can you note that the OS_WIN code is fine for USE_AURA too on windows then?

Done.
