I think it's a much better idea to add the callback you need to AllegroMP3, 
AllegroOGG and alogg. (Side-note: there are two distinct libraries, one 
called AllegroOGG and one called alogg.) Allegro shouldn't be working around 
bad design* in libraries that are on top of it. If you are releasing source 
code, you might like to include patched versions of Allegro{MP3,OGG} in your 
project, and require that the user have a standard version of Allegro 
available.

*Arguably the design is not that bad, since AllegroMP3 and AllegroOGG are 
actually very simple layers on top of underlying mp3 and ogg decoding 
libraries. If you want something more complex, there is no reason not to just 
use the raw libraries (apart from not having thought of it).
