As of BOOST_FUSION_ADAPT_STRUCT without type deduction, there were only simple attributes filler. Now this need more complex logic to handle both API: the backward compatible one with type specificiation, the one without type specification and the non-variadic one which enables omitting the type specification by providing BOOST_FUSION_ADAPT_AUTO instead of the type. That's why I extracted the FILLER_* macros details in a separate source file.
