+//               without them.
+//
+// By using this header your code will get back default values from
+// GetSystemMetrics() for new metrics, and the new multimonitor APIs
+// will act like only one display is present on a Win32 OS without
+// multimonitor APIs.
+//
+// Exactly one source must include this with COMPILE_MULTIMON_STUBS defined.
