Port to Windows

[sldr]

I watched your latest lockfree_mpmc_queue CppCon video, and you mentioned that it hasn't worked on Windows. Well, I ported it to Windows and it works. I need to cleanup some of the rough edges and get the report script running in PowerShell. Take a look and let me know what you think. I did use the MSVC intrinsic _InterlockedCompareExchange128 that uses cmpxchg16b. I also used the Microsoft supplied std::_Unsigned128 and std::_Signed128 classes.

Its forked at: https://github.com/sldr/lockfree_mpmc_queue

After some more work if you are interested, I would be happy to send you a pull request to merge my port back into the original.

Laters,

I did the port for fun. I have always enjoyed programming in a multithreaded, multiprocess, multisystem environments. When I noticed, it wasn't ported to Windows, I thought it would be a fun exercise to port it to my preferred platform.

While I could see some uses at work, they are not using it. I work for a software company that monitors systems and monitors user connections to the systems.
