Are there any compelling reasons to move from 1.1.4 to 1.2.1?  Just curious and no time to investigate for 
myself right at the moment.

As stated on the official zlib site:
# inflate is about 20% faster and minimizes memory allocation
# crc32 is about 50% faster

Ancient?  LOL - it's less than a year old due to some bugs it addressed ;-)

However, I agree with moving to 1.2.1 - with a caviat;

now that zlib1.dll is well defined, and effectively complies with our release
build strategy, I'm committing a patch to use that library

(checking out 1.2.1 in srclib/zlib/ and using make -f win32/Makefile.msc
is all that's needed to employ this version.)

Also, we must obviously distribute zlib1.dll, but in our private directory
tree under apache/bin/.  The only thing I will recommend is that we tweak
Makefile.msc to emit a .pdb file for release builds, with the exact same
optimizations, for later crash analysis.  The binary zlib1.dll will otherwise
remain 100% compatible with the 'official' zlib1.dll - allowing our users to
obtain an updated zlib1.dll without obtaining the latest mod_deflate.so.

The old zlib.dll was pretty horrid.  I think the zlib.org group got it right,
this time around, with zlib1.dll.
