If you run Allegro programs in the console, you need suid root for
everything except framebuffer.  Any user can run an Allegro program
in an X11 window; DGA needs suid root.

Remove the CRs with dtou.

The Allegro library has its own portable filesystem layer.  For
example, instead of findfirst() and the like, I use for_each_file().
