I'm not sure how I feel about defining something in an SRFI with respect to not only C but GCC. Shouldn't the existing definitions be enough? I didn't mean that we should take my "equivalent" verbatim. :) So, we would have to find a wording (if this isn't clear enough from the text and the rationale of SRFI 145) that expresses the same as the C code does. But for people knowing C, the code is certainly the clearest explanation.
