Does it have to be <boost/integer.hpp>, or will using <boost/
integer_traits.hpp> directly (without also including integer.hpp)
also cause the error? (Check both relative orders, of course.)
I wonder if changing numeric_traits to:
//=========================================
template <class Number>
struct numeric_traits
{
typedef
typename ::boost::detail::integer_traits<Number>::difference_type
difference_type;
};
//=========================================
will make a difference. The extra qualification should specify
exactly which "integer_traits" is used. (It was unqualified before,
so maybe the compiler grabs boost::integer_traits if it doesn't know
about boost::detail::integer_traits.)
