Wait a second. The document you link to is a working draft for the next ISO C++ standard, which is by no means yet finalized (planned for 2014 or 2017?). The 2011 standard does not contain any wording to the same effect. Again I would be surprised if this specific paragraph makes it to the final version. Then the initial discussion above was about C, and the ISO C standard does not contains words to that effect at all.
