is that we need more information to decide the exact conditions for whether one ObjCObjectPointer is an acceptable return/parameter override for another, so we're going to disable that entire class of warning for now. The "forward developement" warning category, -Wmethod-signatures, can receive unrestricted feature work, and when we're happy with how it acts, we'll turn it on by default. This is a pretty conservative change, and nobody's totally content with it. llvm-svn: 117524
