C++ is not supported because this proposal came from WG14 (which is not the C++ working group, WG21). There is no such proposal from the C++ folks. I don't know that implementing this right away in the C++ front-end is such a great idea. There will be plenty of proposals that come out of the C working group that are perhaps not fully considered in the context of C++. There is so much potential for unanticipated interactions in C ++ that I think we should be very cautious about implementing C extensions there just for completeness. Cheers, Ben
