Hi Jerry,
I'd also be very interested in finding a way to run Wikidot in a WAMP environment. As you may have read on Wikidot.org, I've been struggling trying to get things working on a Ubuntu server and am not quite there yet.
I'm curious which pieces (libraries?) you've identified that need to be recompiled for use on a Windows Apache server? I've been spending all of my time with my Ubuntu server and haven't tried a WAMP install. Although I'm much more comfortable on a Windows system, I figured it would be better to get it running in the environment it was originally designed before trying to get it to run in Windows!
Good luck with your efforts and keep us posted.
Thanks,
-Ed
