I think we would have to provide the alternative as a built-in Allegro 
feature (like for the 3rd button) if we ever decided to support the 4th 
button.

I agree. We must provide built-in emulation of the buttons up to the number 
we support. Currently this number is 3 and we provide built-in emulation of 
the 3rd button on 2-button mouses.

The MacOS X port has just been merged in the CVS repository so I want it to 
stabilize a bit before we start modifying the core functionalities. But, 
honestly, I find this 4th mouse button dumb, to say the least. Why not put a 
whole keyboard on the mouse then?
