Yes.  However, this might also happen if the user compiles on systems
that don't have zlib for whatever reason.

Solution 3 is the way to go, of course (and thanks for your
willingness to work on it :-).  However, as a temporary measure, maybe
you could add some #ifdef stuff until you are done with updating the
internal zlib?  `FT_CONFIG_OPTION_SYSTEM_ZLIB' is a user option, and
it has to work both switched on and off.
