-Wunused-local-typedefs warnings with GCC 4.8.1

[Torquil Sørensen <torquil@…>]

I'm getting many warnings "-Wunused-local-typedefs" when compiling with GCC 4.8.1 using the latest Boost SVN sources:

/mn/anatu/cma-u3/tmac/usr/include/boost/multi_array/concept_checks.hpp: In static member function ‘static void boost::multi_array_concepts::detail::idgen_helper<N>::call(Array&, const IdxGen&, Call_Type)’:

bump. I am not skilled enough to figure out of to cleanly suppress this warning, which is quite annoying. Any chance for a patch?
