Windows Compile Help

I'm hoping someone can point me in the right direction with an issue I'm
having compiling Subversion on Windows 10 using Visual Studio 2015 tools.

I decided to break out of my comfort zone a bit and see if I could get the
changes in for the py3c dependency added on the Windows side, but I am
*not* a Windows dev. I've done a lot of learning, which as been fun, but I
can't figure this last error out. I've attached the error log, and my WIP
visual studio script that basically got me this far.

It seems to complain the it can't find a handful of symbols related to
zlib, but if I look at the static archive I see those names (though there
are all those different calling conventions on windows, so maybe that is
related to my issue?).

Anyway, I've run out of ideas and was hoping for a little nudge.
