It's apparently an issue when you have zlib 1.2.1 installed somewhere, since in that version zutil.h is considered an "internal" header and is not installed by make install:
http://issues.apache.org/bugzilla/show_bug.cgi?id=28673
so that's a good motivation for not using it too.
Hmm. How are you legitimately supposed to set OS_CODE then if you don't have the header? (I know we hacked around that, but the rationale was that it was an installation error not to have it....) If they truly removed it now and don't have a way to even get the OS_CODE #define, then yah, I guess, let's toss it and hard-code to 0x03.
