[boost] [type_traits] is_pointer<noncopyable> fails on CodeWarrior 9.4

Hi,

The following program produces a compiler error on CodeWarrior 9.4 (see error
messages at end):

    #include <boost/noncopyable.hpp>
    #include <boost/type_traits.hpp>

    int main()
    {
        bool b =  boost::is_pointer<boost::noncopyable>::value;
    }

If I change this to:

    #include <boost/noncopyable.hpp>
    #include <msl_utility>

    int main()
    {
        bool b =  Metrowerks::is_pointer<boost::noncopyable>::value;
    }

everything is fine.

What's up?

Jonathan
