If you have an environment to develop application in C then it should be
relatively easy to compile the zlib library and link it to your program,
but the C language and its standard library and the typical extensions
to it do not usually include zlib by themself; and if you write in Java,
there are comparable libraries available where the same holds true, but
the out-of-the-box experience is different. So this does not seem to be
a fair comparison.

A better comparison would be among independent DEFLATE implementations;
that way we could at least tell how zlib-specific the relevant features
are, and if they are very zlib-specific and not commonly implemented in
independent implementations, they might make bad mandatory features. My
http://bjoern.hoehrmann.de/pngwolf/ for instance uses the DEFLATE imple-
mentation in Igor Pavlov's 7-Zip library, which I believe is the best-
compressing free software implementation; that would be a good candiate,
among others.
