Recently the runner was changed, but the post library wasn't updated - it's built on a different MacOS version. Perhaps the warnings are caused by this?

I already updated the runner in post-rs too, but I haven't created a new release yet. How about trying with libpost built on macos-13 first?

Maybe, but the previous runner was macos-12 and normally libraries built on older versions should work fine to use on a newer macOS.

I thought the warning fix would be a simple one line change of of the Makefile, but the fix broke the linux build and since it's not super urgent to get rid of the warnings I wasn't planning on continuing this for now.
