I would recommend to learn Git then. It is everywhere and that is a skill paying off:

I would like to keep this on the list so that others can join in and help to catch any newly introduced bugs early.

And yes, I would like to see support for Windows, too.

It might simply be that mmap() is not supported on Win32. I am not sure if that architecture even needs to be supported by us at all. Is there even one officially supported version of Windows that is still 32 bit?

I would prefer to avoid pulling in a third-party wrapper for mmap() if we can find a different alternative. Those things tend to break really quickly.
