As the BOOST_FUSION_ADAPT_STRUCT_FILLER* macros were changed to handle type deduction, this breaks the usage that BOOST_FUSION_DEFINE_STRUCT makes from them. That is BOOST_FUSION_DEFINE_STRUCT_IMPL expects a simple tuple, while we now provide a tuple containing the size of a nested tuple which either has or not the type provided. But in the case of the DEFINE* macros it would be a non-sense to support this kind of API as a field being defined cannot be deduced. :)
