For C++ do you mean C++98, > C++03, C++11? My first sentence was unclear, but contained the answer: C++98. And compatible with more recent versions of the language. At some point I suppose we will be able to drop C++03 and require at least C++11, but there's no urge for this. > All of these are relatively old.I expect that D and Java have the same > uncertainty. > > That you use relatively old versions is meaningless because you haven't > specified the version.

What are you exactly referring to here? I am not aware of any case where the semantics are actually altered. I do agree the skeletons should specific their language requirements, you are absolutely right. But I dispute that changing the target language version (e.g. KnR to C90) ever changed some semantics. It certainly broke builds for people who were still using KnR C in 2012, but it did not alter semantics in practice. > This is no more than a single line in the document and/or part of --help.

So I will complete their documentation, yes. Cheers!
