New Revision: 85089
URL: http://svn.boost.org/trac/boost/changeset/85089

Log:
Temporary disable noexcept detection for move assignment for Boost.Variant (exception specification detection for assignment requires call to is_nothrow_move_assignable for each type. But GCC 4.6 fails to do that and complains about incomplete types ) (refs #7911)
