Adding zlib might silence the warnings, but the debugging symbols are
stripped later on anyway (and there=E2=80=99s no =E2=80=9Cdebug=E2=80=9D ou=
tput.)  So either way
is fine, IMO.

(In the future it would be nice to systematically compress debugging
sections that go to =E2=80=9Cdebug=E2=80=9D outputs.)
