As you know, we can't delete the zlib code as we still need it for other 
platforms, Windows mostly. From a brief scan of your patch (not a 
detailed review, too busy at the moment) then it looks like you've added 
a SYSTEM_ZLIB option to select (at build-time) whether to compile the 
version in the jdk repository or not. This approach make sense to me and 
should be separated from the changes needed to use an alternatively 
named zlib (which I think is what Intel IPP will require, assuming it 
can't be picked up by setting LD_LIBRARY_PATH).

In any case, I think both efforts require 7188852 and I see Sherman has 
a review out on that.
