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.
You mean something like this?
#ifdef FT_CONFIG_OPTION_SYSTEM_ZLIB
err = inflateInit2( &stream, MAX_WBITS|32 );
#else
err = inflateInit2( &stream, MAX_WBITS );
#endif
Basically, support the gzip header only if a system installation of
zlib is being used.
