-// We need to undo a macro defined in Windows.h, otherwise we won't compile:
-#undef GetCurrentDirectory
-
-// Windows happily accepts either forward or backward slashes, though any path
-// returned by a Win32 API will have backward slashes.  As LLVM code basically
-// assumes forward slashes are used, backward slashs are converted where they
-// can be introduced into a path.
-//
-// Another invariant is that a path ends with a slash if and only if the path
-// is a root directory.  Any other use of a trailing slash is stripped.  Unlike
-// in Unix, Windows has a rather complicated notion of a root path and this
-// invariant helps simply the code.
