Compilation fails after including reverse_fold.hpp

[Christopher Hinz <hinz@…>]

After including the header file for reverse_fold, compilation fails with the error:

In file included from /usr/include/boost/fusion/algorithm/iteration/reverse_fold.hpp:35:
/usr/include/boost/fusion/algorithm/iteration/detail/preprocessed/reverse_fold.hpp:16:29: error: unknown template name 'result_of_with_decltype'
          : fusion::detail::result_of_with_decltype<

Unlike fold.hpp, reverse_fold.hpp never includes the corresponding header file for result_of_with_decltype.

The error can be reproduced with the following code:

#include <boost/fusion/algorithm/iteration/reverse_fold.hpp> 

int main()
{
}

This bug also affects reverse_iter_fold.
