[gNewSense-users] Copyright, but no license: Free or not?

[Matthew J. Fisher]

I've come across a few files in the kernel which have copyright
statements, but no license. Would these be considered free or unfree? 

The copyright statements don't actually say that any rights are
reserved. They simply list the authors and copyright dates.
