Yes, maybe I was mislead my this piece of information form the Allegro
docs...

If you are programming in C++ you will get an error because the dat field
is
a void pointer and draw_sprite() expects a BITMAP pointer. You can get
around this with a cast, eg:

   draw_sprite(screen, (BITMAP *)data[THE_IMAGE].dat, x, y);

Anyway, I had some bad experiences with pointers while programming under
windows 3.1 and I put explicit casts to avoid problems every time I can.
