I don't get it either. From sibling comments here I think that it's the fact the bulk of his answer was about C++ while the question was about C. But he noted that in his answer and separated the cases, so I don't see what was all the fuss about. It's certainly not a really bad answer, like that Lundin guy says in the comments.
