Same for all the other ones.
Maybe this is worth putting on top of the extern "C" blocks (splitting them if necessary) to reduce littering attributes everywhere?
Note that doc_cfg doesn't work with glob imports, so documenting everything in ffi with these is going to be a huge pain.

Hmm. For now I'm going to keep it like this, but I agree it would be nice to find a long-term solution.

The cfgs in this entire block don't do anything because the entire module import is already gated with #[cfg(all(Py_3_8, not(PyPy)))] (https://github.com/PyO3/pyo3/blob/main/src/ffi/cpython/mod.rs#L43).

As above will remove that gating and make the cfgs here meaningful.

These functions were in Include/pystate before 3.8. The problem with moving this here now is that the cpython/pystate module is gated behind Py_3_8, so this removes it from 3.6 and 3.7, which is why CI is now failing. (the same thing may be true for other things)

Ah. I'd rather have the ffi modules look as much like the Python headers as possible, to minimise confusion. So I'll remove that version gating and tweak things.
