[cfe-dev] help running clang tests on Windows

[Thompson, John]

I've been unable to run the clang tests on Windows for years.  Usually I go to a Linux VM to do it.  Could someone help me get it to work on Windows?

I right-click build on "check-clang" in VS.  The relevant tail messages:

56>  Running the Clang regression tests

If I run it from a cmd window:
