We run in That Other OS!

After some tweaking (not as much as we expected), Micah and I managed to compile and run pgserver on That Other OS (the one most people use, even when most people know it sucks). There is a screenshot, and the binaries are available in the standard location.

The process is documented in the wiki at BuildingWithMinGW
We haven't even tried to build cli_c or the apps yet, as the project that made me do this will run with cli_python. It's probably not too hard.
You will need a fresh checkout from svn of pgserver and cli_python, to get our fixes.
If you prefer to download the binaries, they're in two files. There is pgserver.exe itself (gzipped), which is enough if you have a running cygwin environment and SDL.dll, and there is cygwin-dlls.zip which is everything you need if you don't want to install cygwin.
