[LLVMdev] lit test suite on Windows always hangs.

I'm using Windows 8.1, and every time I run check-clang, I eventually end
up with a bunch of hung processes.  Generally this is an instance of
clang.exe, a bunch of instances of FileCheck.exe, and occasionally an
llc.exe and an opt.exe.

Inside, the processes are all hung inside of calls to WriteFile()
attempting to write to stdout.

I notice some of the tests fail with output indicating that it expects a
unix-like environment.  For example:

207>  ********************
207>  FAIL: Clang :: CodeGen/2004-06-17-UnorderedCompares.c (1109 of 7263)
207>  ******************** TEST 'Clang ::

207>

207>  --

207>  ********************

Any suggestions?

Do you have GnuWin32 installed, and on your path? You may want to look
at http://clang.llvm.org/get_started.html under the Visual Studio
section (the information applies to llvm as well).

Thanks, I wasn't aware of that requirement!  I wonder if this should be
mentioned on the llvm getting started page as well, as I had never seen
this page.

I think that for tests that are dependent on grep, it might be nice to convert
them to FileCheck in the longer run.  This might help make it possible to avoid
the dependency on GNUWin32.
