OK, also there is the concept of a "public interface", which does not
seem to be mentioned in the GNU FAQ. For example the linux kernel
headers are a "public interface", such that they are non-copyrightable
and userspace programs can use them and yet can have non-gnu licenses.
This is mentioned in:
http://www.linuxjournal.com/article/1297

Are those kernel headers explicitly declared as "public interface"
somewhere, or else how do you distinguish a "non-copyrightable public
interface"?

Thanks,
Bahadir
