GTK won't build with strict-prototypes due to gtkitemfactory.h:

    /* We use () here to mean unspecified arguments. This is deprecated
     * as of C99, but we can't change it without breaking compatibility.
     * (Note that if we are included from a C++ program () will mean
     * (void) so an explicit cast will be needed.)
     */
    typedef	void	(*GtkItemFactoryCallback)  ();
