There is really no portable way to do this, without using the INT 33
function.  There may be another function that you can use besides 0, but
I'm not familiar with the INT 33 interface, and my Mouse Programmers Ref.
is buried under piles of other books right now.

Since you only need to do this once, I suggest that you do it at a time
in your proram while you are waiting for the user.  For example, if you
display a startup screen, do it while they are reading that, or if you
ask them for some input, do it then.

BTW, how long is the delay? (define substantial)

	The problem that I am having is that I am linking together several
.OBJ files, and I don't want to declare a variable as global (for reasons
too detailed)...  The delay is only about one second, but that interrupt
also resets the mouse, which I don't want to do...

	Many programs have their own drivers built-in; how do they determine
the number of buttons?  I guess what I'm looking for is information that
is related to ports, etc.  i.e. send a value to the serial port+1, look at
top three bits, whatever...
