[Boost-users] use of boost::noncopyable ?

1>V:\Trunk\stable\src\Include\Tools/unique_RAII.h(61): error C2248: 'boost::noncopyable_::noncopyable::operator =' : cannot access private member declared in class 'boost::noncopyable_::noncopyable' .... This diagnostic occurred in the compiler generated function (the normal copy constructor) That kind of defeats the purpose, doesn't it? I have to declare a dummy copy constructor to get the class to compile.
