Since the eboard project is hardly maintained, an upstream patch is currently difficult to implement. Therefore I consider to take the tip to heart and to change to USE_STDCXX=gnu++14 in the games/eboard port. The port builds well, the program seems to work without errors. Still, one more question: is it safe to remove USES=compiler:c++11-lang for architectures other than amd64 and i386 and just use USE_STDCXX=gnu++14. I have no way to test for arm, etc. Thanks for clarification.
