your pointers can't access more then 64K at a time, you will want to set
MAXSEG_64K in zlib.h. Since it is unlikely that the method of handling
memory allocation on a platform will change between applications, these
functions must be modified in the library at compile time. If you prefer
to use a different method of allocating and freeing data, you can use

+your own functions as described above.
