After starting up some tests to make sure the Windows version of Deadwood works, I discovered that, for whatever reason, the Windows build of the snapshots do not work. 2.3.03 and 2.4.01 work just fine in Windows; and the latest snapshot works just fine in CentOS Linux 5. It's only in Windows it doesn't work.
I will figure out what's broken and fix it; once I do that, I can release Deadwood 2.4.02.
