Build failures on 0.16.0-dev

[ringtailsoftware]

Using zig 0.16.0-dev on Mac aarch64 fails to build. From looking at TargetConditionals.h it seems like the C compiler doesn't have the #defines to know which platform it's targetting.

Sounds like the same issue as castholm/SDL#29, check if the workaround there works. Either way it's a bug with how Zig handles macOS headers. It looks like the linked issue has an open PR that will close it so I think I will just wait for it to get fixed upstream instead of adding any workarounds.

Updated the examples to d430f78 and have confirmed that they build on Mac with latest Zig master.
