* xterm.c (x_convert_modifiers): Declare this to return an
	unsigned int, not a Lisp_Object.  Remember that the quiescent
	value for part is Qnil, not zero, that x_mouse_x and x_mouse_y
	are ints, not Lisp_Objects, and that RESULT->x and RESULT->y are
	Lisp_Objects, not ints.
	(XTread_socket): Declare this to return int, not Lisp_Object.
	When calling construct_mouse_click on a non-scrollbar click, pass
	PART as Qnil, not zero.
	(x_calc_absolute_position): Remember that x_screen_width and
	x_screen_height are ints, not Lisp_Objects.
