Migrating ATL code to VS 2008

Hi,
I'm trying to migrate ATL code from VS 2003 to VS 2008.
I've encountered a problem compiling my code.
It seems that it is a "C++" problem, but I post it here since some of
you may encountered it.

The code snippet is very simple.
A class "CDerived" is derived from CWindowImpl.
The inheritance is "protected".
To avoid compilation errors, the "friend class..." line is added.

This is the code, which compiles fine on VS 2003:
=======================================
#include <atlbase.h>
#include <atlwin.h>
class CDerived : protected CWindowImpl<CDerived>
{
    friend class CWindowImpl;
public:
    void CreateA()
    {
        Create(NULL);
    }

    BEGIN_MSG_MAP(CDerived)
    END_MSG_MAP()
};

int _tmain(int argc, _TCHAR* argv[])
{
    CDerived a;
    a.CreateA();
}
=======================================

The problems is, that on VS 2008 compiler:
I get compilation error on the "friend class...":
"error C2990: 'ATL::CWindowImpl' : non-class template has already been
declared as a class template"
And I dont want to change the inheritance from "protected" to "public"

Any help is appreciated.
Thanks,
D.
