+	* scripts/features/reinvoke: Remove invocations of "touch" in

+	Note that UNIX touch behaves the same way if the file already

+
+	* test_driver.pl (run_each_test): In retrospect, I don't like the
+	.lN/.bN/.dN postfix required by DOS.  So, for non-DOS systems I
+	changed it back to use .log, .base, and .diff.
+
+	* run_make_tests.pl (set_more_defaults): Move the check for the
+	make pathname to here from set_defaults (that's too early since it
+	happens before the command line processing).
+	Create a new variable $port_type, calculated from $osname, to
+	specify what kind of system we're running on.  We should integrate
+	the VOS stuff here, too.
+	(valid_option): Comment out the workdir/-work stuff so people
+	won't be fooled into thinking it works... someone needs to fix
+	this, though!
