 Cannot compile keyword.cpp test from Boost.Spirit Repository directory.
 Lot of errors looks like:

 boost/fusion/view/transform_view/detail/value_of_impl.hpp:37:74: error: no
 type named 'type' in
 'boost::mpl::apply<boost::fusion::detail::apply_transform_result<boost::spirit::repository::qi::detail::string_keywords<boost::fusion::cons<boost::spirit::repository::qi::kwd_parser<boost::spirit::qi::expect<boost::fusion::cons<boost::spirit::qi::literal_char<boost::spirit::char_encoding::standard,
 true, false>,
 boost::fusion::cons<boost::spirit::qi::char_class<boost::spirit::tag::char_code<boost::spirit::tag::char_,
 boost::spirit::char_encoding::ascii> >, boost::fusion::nil_> > >, char
 const (&)[2],
 ... too long to be quoted ...

 As a workaround I was able to compile the example with
 -DBOOST_RESULT_OF_USE_TR1_WITH_DECLTYPE_FALLBACK and
 -DBOOST_RESULT_OF_USE_TR1 (any macro is working). Unfortunately, these
 flags breaks the my spirit parser in some other way with lot of other but
 similar errors.

 The real problem may be in Boost.Fusion. The best workaround I can use by
 now is to change the line in boost/fusion/support/detail/result_of.hpp
 from
 #if !defined(BOOST_RESULT_OF_USE_DECLTYPE) ||
 defined(BOOST_NO_CXX11_VARIADIC_TEMPLATES)

 to

 #if (!defined(BOOST_RESULT_OF_USE_DECLTYPE) &&
 !defined(BOOST_RESULT_OF_USE_TR1_WITH_DECLTYPE_FALLBACK)) ||
 defined(BOOST_NO_CXX11_VARIADIC_TEMPLATES)

 to prevent the define of macro BOOST_FUSION_NO_DECLTYPE_BASED_RESULT_OF

 Then I'm able to compile my project with keywords from spirit repository
 together with -DBOOST_RESULT_OF_USE_TR1_WITH_DECLTYPE_FALLBACK
