Thank you Iohannes. I read more carefully the GPL page.

why would there be?

the GPL is a *license*, not a *copyright* (despite it's alias "copyleft").

so any properly licensed (non Public Domain) software contains two things:
- a copyright stanza (who owns the copyright)
- a license grant (under which terms you can use the software)

this is even made explicit in the GPL howto [1]:
