        py-compile: complain on unrecognized options

   - The py-compile script now accepts empty arguments passed to the options
     `--destdir' and `--basedir', and complains about unrecognized options.
+    Moreover, a non-option argument or a special `--' arguments terminates
+    the list of options.
