--- Comment #51 from post+gcc at ralfj dot de --- Oh great, I love it when one part of the C standard just adds exceptions to statements made elsewhere. It's almost as if the authors want this to be as hard to understand as possible... That then raises the question which version of the signature is actually used for building (and optimizing) the function: the one in the declaration or the one in the definition. Does the standard have an answer to that?
