[boost] mpl::equal_to changes

Hi,

Is the following program supposed to compile with the new MPL?  It works
fine with boost 1.31, but apparantly fails in CVS.  But, maybe I was
mis-using equal_to ?

#include <boost/mpl/equal_to.hpp>
#include <boost/mpl/bool.hpp>

int main()
{
    boost::mpl::equal_to<boost::mpl::bool_<true>,
                         boost::mpl::bool_<true> >
    dummy;
}

Error message from CVS is: (thanks to Matthias Troyer for testing it)

../boost/boost/mpl/aux_/preprocessed/gcc/equal_to.hpp: In instantiation
of `boost::mpl::equal_to_tag<mpl_::bool_< true> >':
