           Summary: objc/objc-runtime.h does not exist on all
                    PLATFORM(MAC)
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Other
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Web Template Framework
        AssignedTo: webkit-unassigned at lists.webkit.org

objc/objc-runtime.h does not exist on iOS.  In fact on OSX, the entire contents of this include is

#include <objc/runtime.h>
#include <objc/message.h>

In order to build for iOS, one must either alter the installed SDK or alter wtf/Functional.h.  Altering the SDK is incorrect.
