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-unix-boost-bin-v2-libs-msm-test-History-test-gcc-4-4-3-debug.html

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 ;-)

Thanks,

Christophe
