Michel,

I just looked at the code and saw:

#if !defined(BOOST_MSVC)
    // Iterators >= ForwardIterator must produce real references
    // as required by the C++ standard requirements in Table 74.
    BOOST_STATIC_CONSTANT(bool, forward_iter_with_real_reference
      =
(!boost::is_convertible<iterator_category*,std::forward_iterator_tag*>::valu
e)
                             || boost::is_same<reference,value_type&>::value
                             || boost::is_same<reference,const
value_type&>::value));

    // This check gives incorrect results in iter_traits_gen_test.cpp
    BOOST_STATIC_ASSERT(forward_iter_with_real_reference);
#endif

So, are you certain you have an up-to-date version of the code?
