If the author of the patch is the one that puts it there, surely it is
up to them to make any necessary statements about what license they
want?

BTW, I think the relevant sections of the GPL seem to be section 5
(and that of the LGPL sections 3, 4, 5).

http://www.gnu.org/licenses/gpl.html
http://www.gnu.org/licenses/lgpl.html

If you really stood on ceremony, could you claim section 5b of the GPL
applied to patches?

See also section 4b of the LGPL for possibly relevant conditions.

As I'm not a lawyer, I don't read these licenses very well. Which
categories do patches fall under? Which categories do forks of LGPL
libraries that use part of, but not all of another LGPL library? Which
categories do GPL distributions that include forks of LGPL libraries,
with patches, fall under?

Bill.
