Given the (apparent) amount of confusion here, I'd suggest a dedicated document in Clang's documentation that gives suggested best practices and warns about anti-patterns for detecting these kinds of things. We can write it reasonably generically and make it not too Clang-specific and citable for guidance even when folks are using GCC (or other compilers).
