(I'd also like to know if there's std::ref in <functional> because the specification of the constructor uses it.) But the config library doesn't seem to provide a way. There's no macro for std::unique_ptr, and there's no macro for "generic C++11 compiler and library".

At the moment, I am using:
#if __cplusplus >= 201103L
