1) I agree that we can't have a port with a GPL-incompatible libc.

2) I assert that NetBSD's libc, while under a 4-clause license, qualifies
under the GPL clause exempting system libraries from the linking
limitations (that nailed OpenSSL and others).

Part 2 is why I'm asking -legal.

The actual honoring of advertisement requirements is a separate (though
still important) issue.

This is the 'revised BSD' license.

http://www.gnu.org/philosophy/bsd.html has an example of the clause in
question. I suppose that is the 'positive advertising' clause you're
speaking of, since it requires advertisement of certain things, rather than
denying it.
