> It's harder as we don't know the distinction between declaration/definition at merge time. Right now the C++ implementation of this warning actually checks the attributes too late, after they're merged. I'll take out the C++/C support completely and keep to ObjC in this patch for simplicity. The rest can be supported later.

That sounds fine for now! LGTM
