+## The following tests have been disabled because creating functions
+## on the fly causes trouble (filesystem timestamp resolution?) and so
+## leads people to complain about the failed tests when the dispatch
+## mechanism is working fine, but it is really the creation of the
+## functions that is failing.  And anyway, this method of function
+## dispatch should be considered obsolete and probably removed from
+## Octave now that we have classes.
