Thank you, that seems to have solved the problem. There's something fishy
with the RCS tag, though: it claims to be at 1.6 still:

/*      $NetBSD: _context_u.S,v 1.6 2007/09/07 14:09:29 ad Exp $        */

even though cvs claims it's at rev 1.7. Very odd; I thought those RCS id's
were updated automagically.
