	Anyway, I think du is broken in most of its implementation;
	it seems to have serious problems with links and such.

	A friend of mine's written a realdu utility some time ago,
	on SunOS 4.1.2 -- it also works on 2.1.0.  I think it also
	supports the standard options (for scripts who rely on it).
	
	But it's a bit slower in 'real' mode.

	Anyone interested?
