The last I tried, I could not even step through Clang-generated code
with GDB on MS-Windows.  The line numbers were all wrong.  Admittedly
that was 4 months ago, but I don't see that it's likely for much to have
changed since then.

So this is why I think we shouldn't worry about building on Windows with
Clang.  There are enough real problems to worry about.
