How about:

#define BOOST_NONCOPYABLE virtual ::boost::noncopyable

to be used as

class A : BOOST_NONCOPYABLE {};
class B : public A, BOOST_NONCOPYABLE {};

does anyone see any problem? Is this a bad approach? Should it be added
to boost/utility.hpp?

Another approach, if we don't care too much about namespaces: you could
even rename noncopyable to noncopyable_t and add

#define noncopyable virtual ::boost::noncopyable_t

but I don't like this very much :)
