These
operator!=andoperator==overloads are being removed in C++20 and later modes in the spirit of P1614R2. Also strengthening the exception specifications for some members and friends offpos, given they don't rely on_Statetype.<experimental/*>,<hash_map>, and<hash_set>are not touched, because they are subject to removal in vNext, and it's unwise for everyone to used these components in C++20 and later modes.It seems that MSVC STL delegates test cases for
fposto libcxx, so I haven't added a test...
