Support for building CMake itself with VS 6 and 7.0 (2002) was dropped
recently in 'master' and is not a requirement for future contributions.
It still builds with VS 7.1 (2003).

I don't think anyone is submitting a dashboard with 2.95 anymore.

The general answer is that contributions must build cleanly on the
compilers submitting to the nightly dashboard.

Note that some of them are not actually building CMake anymore, but
merely running the test suite to make sure targeting older compilers
still works.  These include:

- Borland 5.x
- OpenWatcom
- VS 6, 7.0

They are all testing CMake binaries built with newer compilers.
