Fix zlib macro brokenness on osx with zlib 1.2.4 and higher.
From the code: zlib 1.2.4 and 1.2.5 do some "clever" things with macros. Instead of saying "(defined(FOO) ? FOO : 0)" they like to say "FOO-0", on the theory that nobody will care if the compile outputs a no-such-identifier warning. Sorry, but we like -Werror over here, so I guess we need to define these. I hope that zlib 1.2.6 doesn't break these too. Possible fix for bug 1526.
