[cfe-dev] Running the Clang tests on windows

[John Thompson]

There are problems running the tests on Windows.  Even though the are cmake
files in place to generate project files for them, there are some
Windows-specific problems in this and the underlying Python files.  I did a
little digging into it, and there are some problems with encountered "C:",
and perhaps '/'s ending up in the output script files.  (I hacked the
.vcproj files directly to get rid of the "C:"'s, but then still had other
errors, listed in the enclosed file.)

It's pretty clear being able to run the tests is important for Windows-based
clang developer wannabees like me, so I'd like to get this working.  I'm
prepared to try to do this, but I thought I'd better ping everyone to see if
someone isn't already working on this.  I don't know either Python or cmake,
so if someone better prepared is willing to have a whack at it instead, let
me know soon.
