I am not a lawyer, but common sense would say that applying a bugfix
from the zlib developers would not constitute "modifying" the code.

If a user comes up with his/her own bugfix they would not be allowed
to ship it, but certainly they could share it with the zlib developers
and get it into zlib upstream.

Of course, common sense probably doesn't apply...  Bottom line is that
the implications could be "interesting" as Greg said, but probably not
fatal.

Much better would be to persuade Igor to license it to us under the
zlib license.
