The obvious answer is to ask the C++ committee to change their
silly rule. And if they don't want to change it, just ignore it;
the C++ rule is already incompatible with C, now it will just be
incompatible in a different way. The gap between C and C++ has
increased to the point where they should be treated as separate
and independent languages.
