Re: [boost] [config] Need help with clang config

The configuration with the built-in clang++ in C++11 mode should just be disabled; the default libstdc++ on Travis is 4.6 and is too broken for any serious C++11 work.

Looking at the current log, it seems that it can be fixed by disabling for libstdc++ 4.6 on Clang, as this is the only test that doesn't compile.
