OK, I know installed the latest version of boost, which uses
has_new_operator type trait.

But , know I am getting  compiler errors , for this minimal test program :

#include <boost/type_traits/has_new_operator.hpp>
class A {
public:
    void* operator new(std::size_t);
    void* operator new[] (size_t);
    void* operator new(std::size_t, void*);
};

int main()
{
    boost::has_new_operator<A>();
}

The compiler errors are :

Error 1:
  error C2975: 'b1' : invalid template argument for
'boost::type_traits::ice_or', expected compile-time constant expression
\libs\boost\inc\boost-1_41\boost\type_traits\has_new_operator.hpp    100

Error 2 :
 error C2866: 'boost::detail::has_new_operator_impl<T>::s1' : a const static
data member of a managed type must be initialized at the point of
declaration
\libs\boost\inc\boost-1_41\boost\type_traits\has_new_operator.hpp    93

Error 3:
Error    1    error C2668:
'boost::detail::has_new_operator_impl<T>::check_sig' : ambiguous call to
overloaded function
\libs\boost\inc\boost-1_41\boost\type_traits\has_new_operator.hpp    93

If you can see what the problem is
Thank you for your time
