_Py_InitializeRecursionLimits fails on Windows 7 due to absence of GetCurrentThreadStackLimits

[chw0239]

Bug report

Bug description:

The function _Py_InitializeRecursionLimits uses GetCurrentThreadStackLimits to get information about thread stack limits, but according to documentations of windows, this API requires Windows 8+, which will cause programs to abort on startup on Windows 7 and earlier:

The procedure entry point GetCurrentThreadStackLimits could not be located in the dynamic link library KERNEL32.dll

It seems there are some workaround for this API on Windows 7, which works fine on my PC. So maybe we can change this API call to a more compatible version?

CPython versions tested on:

3.14

Operating systems tested on:

Windows

Per PEP 11, we generally don't support Windows versions that have reached end-of-life, but if there's an easy fix, we can consider accepting it.

It doesn't look like an easy enough fix. If you want support for old versions of Windows in new versions of Python, I'd suggest working with one of the distributors who maintain sets of patches.
