Each of the affected libraries can consider this set of names as belonging to the library despite being defined by Config. They also don't seem likely, though I haven't checked, to be used currently. For those reasons I don't see the problem.

The proposed unique tag, CPP, is meaningless. It may create a namespace not already used, but it also doesn't relate to the function of the macros. Since Boost.Config doesn't have its own tag, it seemed reasonable that these not have a tag, which makes them extensions of the affected libraries' macros.

Whether there is a tag, or even if the tag is CPP, the macros appear useful.
