Hello, @yuedong56.
It's a file that contains a weird compound macro to support ARC-or-notd in really old projects that use like the 10.6 SDK, before __has_feature was available. For the gory details, here it is.
Since none of my libraries go back to support 10.6 any more, you should just eliminate that #include and patch any errors which occur by using #if __has_feature(objc_arc)
I cant find it
