Nope, the explicit cast will shut up any warnings. 
Unless you also make sure the callback has the explicit same prototype as
expected so you can get rid of the cast. Which might have been possible (but not
necessarily better coding style) in this case, but is not universally useful
e.g. when connecting gobject signals.
