Re: [boost] [config] Macro for "using" type alias defects

Hi all,

I was wondering if there is any macro in Boost.Config for advertising the defect of the "using" support from the compiler.

I was reported this:

https://github.com/boostorg/test/pull/140

and at the time I wrote the thing, I thought that those guards would have been enough:

https://github.com/boostorg/test/blob/35c9acf5bd38d625ebd45cf940c5b9a19aa229...

(auto, tuple and variadic template sounds to me more difficult to support than "using" template alias).

Would it make sense to have BOOST_NO_CXX11_TYPE_ALIAS?

Why not just use a typedef? I would say, using a macro check would make the code less maintainable.
