0057     VS2014 was skipped in the release sequence for MS. Which

0060     mapping from MSC version to VS product version.

0062     VS2017 is a total nightmare when it comes to version numbers.
0063     Hence to avoid arguments relating to that both present and

0065     version, i.e. cl.exe, as the version number here.
