Can you be specific? There are several different (aged) auto_ptr
implementations, so it may not be the case that the others are in error

Well, maybe I'm missing something, but my understanding is that auto_ptr must be
able to delete the object that it manages. If so, it couldn't take a const ref,
unless it then casts away the constness in order to delete it.
But your very asking this makes me suspect that indeed I must be missing
something...

It's legal to delete something that is const.

Deletion is not class as modifying it. <G>

Doh!  I think I'd heard this before, but it totally left my mind without a
trace; thank you!

Okay Walter, I must retract my earlier retraction, but the kudos stay .. ;)
