 undeclared identifier 'tools'

    typename tools::promote_args<T>::type trunc(const T& v, const Policy&
 pol);

 ----

 promotion includes config, config includes round_fwd, round_fwd includes
 promotion.

 config.h seems to not need to include round_fwd.h, since from what I've
 checked, what it used from round_fwd.h is inside a definition of a macro
 (BOOST_MATH_STD_USING), hence no compile time dependency.
