Well, but the traditional preprocessor behavior in the end is not in not expanding macro arguments, normally they actually are expanded, but not immediately, but because of trying to preprocess the result of preprocessing again and again. When traditionally preprocessing #if/#elif etc. directives, the directive line is preprocessed until no macros are present and only then fed to the ISO preprocessor to evaluate and handle the directive. The problem with the builtin function-like macros is that it needs the argument immediately.
Ah, I see, thanks. Please add some of this rationale to the patch. OK with that.
