We've discussed this before.  I don't think we should check OS
identifiers.  It would be better to have a feature test in the
configure script (or perhaps the run-octave script itself) that
decides when it is needed.  I don't know how to write the test, but I
will consider (review, think about, and possibly accept) a patch if
someone else submits one.
