error C3861: '_PyArg_ParseTuple_SizeT': identifier not found

When I try to migrate my PySide bindings to 6.8.x, the compilation fails with the error message from the summary ('_PyArg_ParseTuple_SizeT': identifier not found).

I have tried to search the internet for solutions, but I didn't find anything.

With 6.7.x everything works fine.

It tried on windows and linux and used python versions 3.9, 3.10 and 3.11 and the compilation error happens everywhere. Maybe I miss a new define to be set or an option for the shiboken code generation?

Hmm. It seems to be connected to the usage of the Py_LIMITED_API define. Formerly, I was just defining it by passing -DPy_LIMITED_API to the compiler. This doesn't seem to work anymore now. I was trying with -DPy_LIMITED_API=03070000 according to https://docs.cython.org/en/latest/src/userguide/limited_api.html and that compiles, but the compiled python module seems to segfault immediately.
