	Bug 520286 - Non-deletable window has no minimize / maximize buttons

	* gdk/win32/gdkmain-win32.c (_gdk_win32_window_style_to_string):
	New debugging output function that decodes a set of WS_* bits.

	* gdk/win32/gdkprivate-win32.h: Declare it.

	* gdk/win32/gdkwindow-win32.c (update_single_system_menu_entry):
	New function that enables or disables one menu entry in the system
	menu of a top-level window. (The corresponding decoration will
	then also be enabled or disabled (grayed).)

	(update_style_bits): Do as the comment says and don't try to
	update the window style based on the GdkWMFunctions set for the
	window.

	(update_system_menu): New function that enables or disables the
	system menu entries based on a window's stored set of
	GdkWMFunctions.

	(gdk_window_set_functions): Call update_system_menu() instead of
	update_style_bits().
