Thanks Costin,
        I've found a workaround now, but I might try the cvs head anyway.
With a bit of luck HP's fix, whatever it was might have got in there.

[Ashton, Bruce]         I'll have to negotiate with the Unix team (I'm part

        [Ashton, Bruce]  I can't add a printf before, this line, the
