I'll check them and see what I can do.

The problem is that the docs never mentioned the driver defines 
disappearing if Allegro is compiled without support for that driver. 
Thusly, code which uses those defines without checking for them (which 
there is no indication that they had to be, and I think is ugly anyway) 
is now broken. The fact that it's been this way pre-4.0 has no real 
relevance.. we made changes to Allegro that causes valid Allegro 
programs to break, so we should fix it.
