Well, if it's in the .orig.tar.gz, of course it's distributed.  It gets
mirrored all over the world.

If it violates the DFSG, it should be pulled from the package, source
and binary alike.

Patents are tricky because in and of themselves they aren't necessarily
violative of the DFSG, both because a patent license may permit
DFSG-free implementations, and because of jurisdictional issues.

I think it is probably better to yank the LZW code from the .orig.tar.gz
and roll a new one.

Whether the DFSG and Social Contract actually *require* you do so,
though, I'm not sure about.
