I've started a first attempt, but I don't have Windows handy to test it on:

https://github.com/schmichael/mmstats/compare/windows-mmap#L0R43

My guess is that 2 things will definitely need fixing:

I doubt the MapViewOfFile is in Window's C library implementation ... perhaps in kernel32?
msync and munmap will probably need fixing as well (although these functions could just be stubs on Windows as they're not 100% necessary)
