boost.config defines BOOST_NO_CXX11_USER_DEFINED_LITERALS but I believe this defect macro could not be used for detecting chrono literals support.
Should the new BOOST_NO_CXX14_CHRONO_LITERALS depend on the compiler or stdlib version? AFAIK chrono literals are available since gcc-4.9.3 (clang?, intel?, msvc?).
It's a bit of both - certainly it's a std lib feature, but it's also dependent on the compiler being in C++14 mode I assume?
I'd like to make the defect macro depend on the compiler version - gcc got a fix in gcc-4.9.3 that made the chrono literals useable and stdlib configs in boost.config do not specify/use patch levels as the compiler configs do.
