Apparently not everyone has gotten the message.
lexical_cast.h is included from boost/graph/graphml.hpp
any.h is included from contract.

Here are the files that failed to compile:

Looking at the meta/libraries.json files.
Boost.Contract has no language requirement
Boost.Graph requires C++03.
Boost.ProgramOptions requires C++11  — so why is it getting built?
Boost.Thread requires C++11  — so why is it getting built?
