Replacing all overalods of operator== by something like

template<class A0, class A1>
typename enable_if<
   mpl::or_< is_base_of<iterator_range_base, A0>, 
is_base_of<iterator_range_base, A1> >
, bool
 >::type operator==(A0 const& a0, A1 const& a1)
{
   return boost::equal(a0, a1);
}

should allow to fix the bug above.
