+	* gtk/Gtk.metadata: mark the SpinButton::Output signal as manually
+	marshaled to avoid a compat break.  The old manual marshaler expected
+	and int RetVal and the new signal closure more accurately expects a
+	bool.  Since returning 1 previously worked, we need to revert to the
+	int expectation, even though bool is technically more correct.
