@jgonzalezdr Do you mind giving this a look when you have a chance? I think I've retained the behavior you added in #1538, but I'd like confirmation since I'm not...

I'm gonna get this under test in CI before I reopen this.

#1624

Best I can tell, it never worked. I tried bisecting to find the regression, but I cannot find a working version. Please correct me if I'm wrong.

Solved by #1629.

I've demonstrated backwards compatibility in the [cmake_coverage build.](https://github.com/cpputest/cpputest/runs/7265204469?check_suite_focus=true)

Are these warnings related to #1605?

It looks like Apple Clang supports `override` even in C++98. See #1612.

Namespacing is addressed in #1624.
