Thank you so much, PhoebeHui, Hoikas and NancyLi for helping! I applied your requested changes.

If it's possible, can I try compiling and testing this on macOS tomorrow? (since it's 04:31 am here) I can then confirm if that works or not.

Of course, you can do this at any time available for you. It's too late for you now. Please have a good rest first. You can update it tomorrow if it can support osx.

I looked further into this and tried to compile it, and I'm sure it would make no sense to support macOS. This library was never intended to work for Mac since you need to use a user-space driver thats only available for Linux. On top of that, there's no X11 support for Mac anymore which is required (It's XQuartz now for quite some time). The commit was from 2013. I think Blender uses the proprietary driver on Windows and Mac and libspnav on Linux.

I'm happy with the port! The only suggestion I could think of is maybe adding a comment explaining the confusion between ref v0.2.3 and libspnav-0.2.3

Thanks for your further investigation about this new port. It's so great.
I agree with your point that adding a comment to explain the ref.

Thanks for your contribution!
