I haven't looked in detail, but it looks like those two overloads were added in C++14 and need guarding with a suitable #if __cplusplus >= C++1Y_version_here
Yep - that’s what’s happening here. Also, there are two implementations of the same routines; one in cxx11/is_permutation.hpp, and the other in cxx14/is_permutation.hpp. I’ll clean that up - thanks for letting me know. — Marshall

I think I’ve got this done. If you see any more issues, please let me know. — Marshall
