The docs list no test results of the current version on Windoze. Is there anything I can do to fix this?

It's "Windows", for what it's worth.

As ikegami stated, fork() does not work within the Windows OS, so it isn't surprising that a) there are no test results for the distribution and b) unit tests fail on a Windows system.

Use an OS that inherently uses fork to create separate processes, or use threading.
