the defines in question are internal to zlib.  packages relying on them are 
broken, plain and simple.

the *only* code that broke was code that was copied out of the zlib tree and 
directly imported into other projects -- minizip.  because the code was 
designed to be compiled & linked as part of the zlib project, it uses internal 
zlib defines.  projects copying the code into their own tree and not cleaning 
things up made a mistake.

for many, this is a direct violation of Gentoo policy and they should be fixed 
to use the minizip code that zlib exports.  for the rest that modify the code 
heavily, they should stop using the internal defines since their own code base 
doesn't support pre-ansi C compilers.

and those fixes can be sent to the respective upstreams

send the fix to the upstream maintainer

because you keep presenting the same flawed ideas and ignore the responses.  
in fact, all of the answers i posted above i already posted to the bug.
