    VS2014 was skipped in the release sequence for MS. Which
    means that the compiler and VS product versions are no longer
    in sync. Hence we need to use different formulas for
    mapping from MSC version to VS product version.
 
    VS2017 is a total nightmare when it comes to version numbers.
    Hence to avoid arguments relating to that both present and
    future.. Any version after VS2015 will use solely the compiler
    version, i.e. cl.exe, as the version number here.
