But IMO *we really must know* which of std:c++14 and std::c++lastest (and others including c++11, c++17) are being specified for the compiler to use.

The compiler version _MSC_FULL_VER = 190024123 does not tell you this - only that it is VS 2015 update 3.

Seems like _MSVC_LANG is 201403 and _HAS_CXX17 is 1 with /std:c++latest. _MSVC_LANG is 201402 and _HAS_CXX17 is 0 with /std:c++14.
