no type named 'tag' in 'boost::fusion::result_of::size<const boost::fusion::single_view<boost::spirit::unused_type> >'

[Peter Schueller <ps@…>]

Something between [73158] and [73126] in the release branch causes the attached program to fail with g++-4.5 and clang-2.9 (showing the clang error message here).

Trunk is fine.

Could be an MPL issue and not a spirit issue. I think the problem already existed in trunk and simply was not merged yet.

Thank you, fix was merged between [74322] and [74331]. Now everything works again!
