I think the best way to do that is to add an API function which
let the user to set a handler for outputting messages, which 
overrides the default behavior, like glib does. In glib you 
have i.e g_message() with a default behavior, but you can override
it calling g_set_message_handler() with a function that receives the
message string and returns nothing.

This approach is very powerfull because you can process and redirect
output whatever you like. Specially on GUI applications, you can 
redirect messages to some GUI widget.
