Having found the relevant release note:

https://developer.apple.com/documentation/macos-release-notes/macos-13-release-notes

I can add a bit more info.

1) The build failure is only seen if you are using the macOS 13 SDK.  It 
has been possible to build with the 12.3 SDK.  But if you don't yet have 
the macOS 13 SDK you are likely to get upgraded to it soon.  Look at

ls -l `xcrun -show-sdk-path`

to see what you have (it is a symlink, to MacOSX13.0.sdk on my system).

2) If you are, a workaround is to add something like

-mmacosx-version-min=12.0

to CFLAGS.
