I haven't svn updated and recompiled in a couple days, but from what I can tell a revision or two ago in several files (I haven't found them all yet) the macro definition for windows was changed from _WIN32 to _WINDOWS which completely breaks compilation on Windows 7 x64 under Visual Studio 2010 Pro targeting the x32 debug build.
I'm currently going through and fixing this in my source to see if anything else is broken.
Edit 1: Turns out this modification was done approximately 170 times. Source compiled fine after a Find and Replace All.
Edit 2: Well after the Find and Replace was done the only error I have left are linking errors for World and Zone stating that perl514.lib is missing. Was there a perl upgrade I missed somewhere? lol
