NSBezierPathElementCurveTo deprecation errors when building pyobjc-framework-Cocoa

[mrpippy]

Describe the bug
When building pyobjc-framework-Cocoa, I get the following build errors:

I don't get this warning/error on my system, and don't understand why. Could you check which compiler is used (e.g. which gcc)?

Could you check if you still get the error on the current tip of the tree (which includes a prospective fix that I just pushed).

One more question out of interest: What is your use case for building from source? I also provide binary wheels on PyPI.

Thanks for the quick reply! Your latest commit does fix the issue.

gcc was pointing to ccache installed through Homebrew, but removing that from PATH did not make a difference.
Are you still running macOS 13, or maybe MACOSX_DEPLOYMENT_TARGET is defined?

And we don't have a specific reason for building from source, but we build the rest of our product from source, it's easy to mirror the Git repo locally, and makes it really easy to test out new versions.
