An alert box like allegro_message would be very easy of course.

True. Will add a function to cancel the current dialog.

I initially had it so the creation function would return an
ALLEGRO_EVENT_SOURCE, and you would only pass back the event. But it
seemed to go a bit against the idea to make this as simple to use as
possible. Calling the dialog would then look like this:

ALLEGRO_EVENT_SOURCE *filechooser = al_spawn_native_file_dialog(path, patterns, mode)
al_register_event_source(queue, filechooser);
...
if (event.type == ALLEGRO_EVENT_NATIVE_FILE_CHOOSER) {
   count = al_finalize_native_file_dialog(&event, result, 1);
}

Guess it's not that much more to type, and the advantage is that there
would be no possibility to access a removed queue.
