I disagree. Allowing unnamed parameters would address the exact problem stated in the question. I don't see how multiple definitions under control of a C preprocessor conditional would make a difference. If an "unused" parameter is used in the function body, you have a bug waiting to happen. It would be better to have it unnamed to allow the compiler to spot the mistake. If you turn the argument on its head, why does C require parameters to be named? There doesn't appear to be any logical reason for this rule. > And there are > variables besides parameter names that are important to > mark UNUSED in certain circumstances. I assume you are referring to unused function return values? I don't see how this is relevant to the original question. -- Ian Collins
