[AD] Windows fixes

[Trent Gamblin <trent@xxxxxxxxxx>]

I have attached a patch that allows Allegro to be compiled on Windows
with MinGW and cmake. Here is an explanation of what I've changed and why:

I removed the event type parameter from src/win/wkeybdnu.c. I guess the
format of the function has changed.

I removed src/c/cmiscs.s from the Windows compilation. The file is meant
for DOS only.

I added the "binary directory" to the include path in CMakeLists.txt. It
is needed to find asmcapa.h.
