Re: [boost] defect macro for thread_local?

does boost provide a defect macro for thread_local (like BOOST_NO_CXX11_THREAD_LOCAL)? I couldn't find something similar int the boost macro reference. The macro would be helpful together with the feature-check to exclude compilers, that do not support the keyword thread_local (as gcc-4.7. and apple's compiler), from unit-tests.

I've just added this to Boost.Config in develop. Let me know if there are any SNAFU's. John.
