python3.14t -m pip install pywin32 fails

Last time I checked, 3.13t at least built, but failed very early on tests. Unsurprising given that pywin32 relies heavily on the GIL. Looks like PyOVERLAPPED->ob_refcnt was removed in 3.14t, so now it doesn't even build at all.

Good luck if you intend on working on free-threaded support !

See pinned issue for (short) discussion: #2303 (comment)

Also for ARM64 cross-compilation, you'd have to update https://github.com/mhammond/pywin32/blob/main/.github/workflows/download-arm64-libs.py to download from https://www.nuget.org/packages/pythonarm64-freethreaded instead

Or wait for #2581 to be merged first since that'll sidestep cross-compilation on free-threaded.

@cclauss Mind if I close this as it's not actionable as-is? There's a ton more work involved than just updating the workflow file. And there's already an issue for tracking this request.

Closing in favor of:

• Free-threaded support? #2303
