There is an often overlooked bit of 'fine print': _compiler support_ for a C++ standard is not the same as the _compiler shipping a complete library_ for that same standard. This can be frustrating. See the release notes for gcc/g++ and clang/clang++, IIRC they usually have a separate entry for C++ library support. In this case, can probably rely on LinkingTo: BH which has been helping with Boost headers for over a decade. Writing R Extensions is also generally careful in reminding us that such language standard support is always dependent on the compiler at hand. So package authors ought to check, just like R does via its extensive configure script when it builds.
