--- Comment #2 from Richard Geary <richardg.work at gmail dot com> ---
This is still present in g++ 5.3.0, and also affects
std::literals::string_literals. The flag -Wno-literal-suffix does not turn it
off.  Thus -Werror builds will fail, despite the C++ being clean.

A workaround is to use 'using namespace std::literals::chrono_literals;' but
having a 'using namespace' in a header file is usually considered bad practice.

Please can someone fix this?
