This can be fixed by simply removing what John added.
The correct thing to have added would have been:

  #include <boost/mpl/integral_c.hpp>

  template <class T, T val>
  struct integral_constant 
    : mpl::integral_c<T,val>
  {};

This would ensure compatibility with existing code that uses
integral_c for tag dispatching.
