OK, let's compare the alternatives:

[1]

class X // noncopyable
{
public:

// ...

private:

// ...

    X(X const &);
    X & operator= (X const &);
};

[2]

#include <boost/noncopyable.hpp>

#ifdef _MSC_VER
#pragma warning(push)
#pragma warning(disable: 4511) // copy constructor not generated
#pragma warning(disable: 4512) // assignment not generated
#endif

class X: private noncopyable
{
public:

// ...

private:

// ...

}

#ifdef _MSC_VER
#pragma warning(pop)
#endif
