While compiling the rtos test-cpp-api.cpp

    {
      auto th9 = rtos::make_shared<thread> ("th9", func, nullptr);

      th9->join ();
    }

the 7.1 version of GCC issues:

Apparently the message is only a notice that something changed in the ABI, and, if the program is built entirely from sources and does not use binary libraries compiled with older ABI versions, can be safely ignored.

To disable the message, use -Wno-psabi with g++.
