[boost] [variant] Bug in recursive_wrapper_fwd.hpp?

I've been tracking down an preprocessor warning involving the  
redefinition of BOOST_TT_AUX_BOOL_TRAIT_DEF1.  It appears to me, in  
boost 1.33.0, that recursive_wrapper_fwd.hpp is misusing:

#include "boost/type_traits/detail/bool_trait_def.hpp"

The usual include pattern for this header is:

// should be the last #include
#include "boost/type_traits/detail/bool_trait_def.hpp"

...

#include "boost/type_traits/detail/bool_trait_undef.hpp"

But recursive_wrapper_fwd.hpp has:

#include "boost/type_traits/detail/bool_trait_def.hpp"
#include "boost/mpl/aux_/lambda_support.hpp"

...

and no include for bool_trait_undef.hpp.  Is that as intended?

Thanks,
Howard
