A build on XCode 9.4.1 on Drone fails because the standard library (stdlibc++) is lacking the std::nullptr_t type.
I believe this means that BOOST_NO_CXX11_NULLPTR should be defined but is not. It seems to be possible that the compiler supports the nullptr keyword but just that the standard library is to old.
