Replace that with just

        setpgrp;

This does the same thing and will work on all systems.

I think there's a bug here.  Perl is expecting a pgrp arg of 0 to mean
$$, but it doesn't allow an explicit $$.  Even this seems a little odd,
as on neither system I've got available at the moment is it mentioned
that a 0 pgrp means getpid() (they both mention that a 0 pid means
getpid(), though).
