+	* file-io.cc (mkstemp): Add mktemp-based implementation of mkstemp on
+	platforms that do not have it (mkstemp is required by the new help
+	system).
+
 	* TEMPLATE-INST/Array-os.cc: Add "extern template" declaration for
 	Array<octave_idx_type> to avoid implicit instantiation (and duplicate
 	symbols at link-time) [Win32]
