   Get them from <a href="http://getgnuwin32.sourceforge.net/">

+  If the environment variable <tt>%PATH%</tt> does not have GnuWin32,
+  or if other grep(s) supercedes GnuWin32 on <tt>%PATH%,</tt>
+  you should specify <tt>LLVM_LIT_TOOLS_DIR</tt>
+  to CMake explicitly.</p>
 
   <p>The cmake build tool is set up to create Visual Studio project files
   for running the tests, "clang-test" being the root.  Therefore, to
   run the test from Visual Studio, right-click the clang-test project
   and select "Build".</p>
