I've started to fix it in 2.1 by linking against zlib.lib instead of particular
files. I'm not a VC guru so, I'm expecting that someone else fixes my *.dsp and
Makefile.win changes ;)

The changes are in Makefile.win r1.134 and mod_deflate.dsp r1.9.

Thanks for the report.

we've had several changes to mod_deflate since this bug report.  Can you check
whether it builds correctly now, either with 2.0.51 or with mod_deflate from
current CVS?

No, httpd-2.0.52 (win32) with mod_deflate (zlib 1.2.1) does not build.

I've just installed 2.0.52 on my XP box (from source) and I had to fix both 
dsp and mak files to build with zlib-1.2.1. I can provide complete files or 
diff's as needed.

  First, only zlib 1.1.4 or 1.2.3 are safe, all of the 1.2.0-1.2.2 releases
  had published vulnerabilities.

  Second; ASF isn't refactoring, in fact we are keeping binary compatibility
  for the life of httpd-2.0 (and breaking it when we ship httpd-2.2).
  When httpd-2.2 ships, we are linking (and not compiling ourselves) to
  the zlib 1.2.3, or then-current version of zlib.dll.

  So if you want to plug in a different mod_deflate.dsp which will let you
  build the zlib.dll (zdll.lib) and simply link that .dll with mod_deflate,
  grab the current development project file and save it within your httpd
  2 modules\filters\ directory;
