	* win32/gwin32directorymonitor.c
	(g_win32_directory_monitor_callback): Make prototype match
	LPOVERLAPPED_COMPLETION_ROUTINE to avoid warning. Cast
	LPOVERLAPPED parameter to local GWin32DirectoryMonitorPrivate
	pointer.

	(g_win32_directory_monitor_constructor):
	GLocalDirectoryMonitor::dirname is in UTF-8 like all other file
	names in the GLib API on Windows, so convert to UTF-16 and open
	with CreateFileW().
