I prefer this last option.  On Linux I would like messages just to go to
standard output/error, at least as an option (e.g. set an environment
variable).  allegro_message really annoyed me when testing examples for
a release.  I would run an example and it would pop up a message box to
tell me usage information, which I'd have to focus and click to close.
