Re: [boost] Removing old config macro and increasing compilerrequirements.

Correct. But they are in the boost::core library along with other files which do have dependencies. Therefore as boost::config depends on boost::core for only those two files, boost::config gets all the dependencies of boost::core transitively. I'm actually even a bit confused by what you wrote because I thought this would be very obvious.

Sorry, but there is no Boost core library other than what you have chosen to define - one could just as easily place those two files as part of Boost.Config and break the dependency that way. Just saying... John.
