// Modified by Henrik Bach to comply with at least MinGW.
// Ported to Win32 by Jeff Cohen.
// We need to undo a macro defined in Windows.h, otherwise we won't compile:
#undef CopyFile
+#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.
