- Add libstdcpp feature to indicate a platform is providing a libstdc++ implementation ready for use - The existing cpp feature now only indicates a working C++ toolchain without libstdc++. (E.g. still useful for the Arduino compatibility layer.) - Added libstdcpp as required feature were needed - Added some documentation on C++ on RIOT
