[AD] Fwd: fourth mouse button under windows

[Matthew Leverton <matthew@xxxxxxxxxx>]

Hello,

A long while ago, I sent a simple patch to enable a fourth mouse button 
in Windows. I'm forwarding the original message, as I don't think it 
ever received any comments.

thanks,

Is there any reason why the fourth mouse button is ignored? According to the the MSDN doc I read, the structure that is currently being used (I forget the name) has:

DIMOFS_BUTTON0
DIMOFS_BUTTON1
DIMOFS_BUTTON2
DIMOFS_BUTTON3

I've included a copy/paste patch that adds it. I tested under MinGW32 and the "minimalist DX7 headers", and it worked fine.

It looked like buttons 5-8 were part of some extended structure that Allegro doesn't use, but I didn't really look into that.
