The version of ref.hpp currently in cvs fails under VC7 with the
following code:

#include <boost/ref.hpp>

struct X{
        enum E{v};
        void func()
        {		
                E e = v;
                boost::ref(e); // line 8
        }
};

c:\boost\boost\utility\addressof.hpp(21) : error C2893: Failed to
specialize function template 'T *boost::addressof(T &)'
        With the following template arguments:
        'X::E'
        c:\boost\boost\ref.hpp(34) : while compiling class-template
member function 'boost::reference_wrapper<T>::reference_wrapper(T &)'
        with
        [
            T=X::E
        ]
        RDCLibTest.cpp(8) : see reference to class template
instantiation 'boost::reference_wrapper<T>' being compiled
        with
        [

        ]
