	* gtk/gtkprintoperation-win32.c(1713) : fix 'function' : incompatible 
	types - from 'struct _cairo *' to 'struct _cairo_surface *' by
	passing the surface to cairo_surface_show_page(), not the context
	* gtk/gtkprintoperation-win32.c(866) : get rid of warning C4018: 
	'<' : signed/unsigned mismatch by using guint for the loop

	* gtk/gtkmenu.c(gtk_menu_get_property) : property 'menu::active' is 
	an uint, gtk_menu_get_active() returns the widget pointer. Convert
	the latter to the former by calculating the index in menu::children
	Also fix some occurences of g_return_if_fail() where 
	g_return_val_if_fail() was meant
