According to the 0-8 and 0-10 specs, if the queue already exists then  
subsequent declarations with :durable and :auto-delete set ignore  
those bits.

BTW, the same is true for exchanges.

I could not find these provisions in the 0-9-1 spec which is odd.  
However, I imagine these provisions hold true for it too.
