Cython had a report from an abi3audit user over our use of these two macros.

My belief is this is another variation of #85 / #83.

The difference is that in earlier Python versions these macros are defined as a static inline function (and so are OK to use because they're embedded in the extension). In Py3.14 they've been converted to regular (non-inline) functions that are part of the Stable ABI. I think the fact that they've become part of the Stable ABI is causing them to get flagged on earlier versions.
