Well, some of each, in fact.

But I am getting a bit confused here. Take the zlib licence, for example,
which contains the condition:
  3. This notice may not be removed or altered from any source distribution.
The FSF says that this is compatible with the GPL, but I don't understand
how this can be so. It imposes an extra restriction, namely the requirement
to reproduce the zlib copyright and licence notice, in addition to the terms
of the GPL. Can someone explain to me how this can be GPL-compatible?
