All the authors are copyright holders automatically, at least in some or
maybe most jurisdictions. You do not need to add copyright label for
material to be copyrighted. That's why you are not allowed to relicense
the work for example, without other authors' agreement.

The problem is that GPL requires to keep original copyright notices, but
such notices were not present.
