IANAL, but from a legal perspective it's probably better to add your name to the copyright notice. Suppose there is no disclaimer of warranty, then wpaul@ surely doesn't want to be held responsible for this code, whether of not it was derived from his code. The copyright probably also needs to be exact in terms of who owns what part of the code in that case (to make sure it is known who is liable when the faulty code construct is identified). I think the basics do not change when there is a disclaimer of warranty, it's just that most of the details become moot points since none of the copyright holds are liable. Just my unfounded take on this... -- Marcel Moolenaar USPA: A-39004 marcel@xcllnt.net
