DEFINE_EMPTY_DESTRUCTOR_WILL_BE_REMOVED(ScreenOrientationController) (no ; at
the end.)

Is it OK to simply remove the destructor like I did in my second patch set?

[Inactive, 2014/05/27 19:08:22]

Done.

 ScreenOrientationController::~ScreenOrientationController()
 {
 }
+#endif
 
 ScreenOrientationController& ScreenOrientationController::from(Document& document)
 {
     ScreenOrientationController* controller = static_cast<ScreenOrientationController*>(DocumentSupplement::from(document, supplementName()));
     if (!controller) {
         controller = new ScreenOrientationController(document);
         DocumentSupplement::provideTo(document, supplementName(), adoptPtrWillBeNoop(controller));
     }
     return *controller;
 }
