When generating sources for EventSendingController.idl, ENABLE_TOUCH_EVENTS is not defined, so we don't generate bindings for the touch event stuff. There seem to be a few pieces missing: 1. The WebKitTestRunner xcconfig files don't define FEATURE_DEFINES 2. WebKitTestRunner/DerivedSources.make doesn't pass --defines "$(FEATURE_DEFINES)" 3. The script build phase doesn't define SDKROOT or pass --no-builtin-rules like it does for, e.g. WebCore
Same for DumpRenderTree and TestWebKitAPI
