You were right, we weren't linking to zdll.lib for mod_deflate, I'll be
fixing that shortly, and working up the two patches to share, one for the
APR_NO_FILE tweak, one for the stderr quirk with modperl.

Had to push out these binaries first, and also now am struggling very
deep inside MSVCR80/OpenSSL/ActiveState Perl on x64 and a host of bugs
that some of the perl packages have, assuming they can pack pointers
into int's and back out again.  Sorry that mess left me distracted from
the issues you raised for most of this week.
