Hi,

While looking at the trunk test results for MSM, I realized (with a shock) that many test cases were not working with g++ any more. The reason is listed in (read the last few lines): http://www.boost.org/development/tests/trunk/developer/output/minion-clang-u...

It appears there is a conflict between mpl and fusion for at. Editing boost/fusion/container/set/detail/deref_impl.hpp from return at<typename It::index>(it.seq->get_data());

to return ::boost::fusion::at<typename It::index>(it.seq->get_data());

Seems to solve the problem in the small example I attached.

This stuff is pretty urgent for me because it breaks a lot of msm tests. How to proceed? The Monday deadline is looming ;-)

Feel free to check in the fix, Christophe.

Thanks! I just did.
