    gdkevents-win32.c: Fix GDK_SETTING event notification on IME change
    
    We need to call g_strdup() on the name that we pass in for notifying the
    GDK_SETTING event so that when we do gdk_event_free() later we will not
    get a crash (stack corruption) that results from attempting to g_free()
    something that is not dynamically allocated.
