Looks great, thanks for implementing this. A couple of questions:

- Is it possible to use it to conditionally compile parts of the libraries? My 
gut feeling tells me that it should...
- Is it possible to add other checks, not covered by Boost.Config? Either by 
adding such checks in the library scope or by some other means?

I'm asking because I have conditionally compiled parts in Boost.Log that 
depend on whether the compiler supports SSE/AVX and message compiler. I also 
have to compile tests to detect that, and I'd be glad to simplify it somehow.
