Python 3.14.0-beta.1 C-extension builds try to link against python314t.lib on non-threaded python

Bug report

Bug description:

I'm completely unsure where the issue stems from (it could be setuptools, https://github.com/actions/setup-python, an actual issue in the first beta, or due to one of pywin32's numerous build hacks which I've been reducing over the years). But since
https://discuss.python.org/t/python-3-14-0-beta-1-is-here/91117 mentions

We strongly encourage maintainers of third-party Python projects to test with 3.14 during the beta phase and report issues found to the Python bug tracker as soon as possible.

And this wasn't happening in alphas, and now does with the first beta. I figured I may as well take a note here.

Mostly copied from pypa/setuptools#4988:

Ever since the Python 3.14 beta 1, pywin32's 3.14 dev builds have started failing. It was working fine in alphas.

Here's the full log: https://github.com/mhammond/pywin32/actions/runs/14912683012/job/41890682321?pr=2582

Of interest is the following line: LINK : fatal error LNK1104: cannot open file 'python314t.lib'. I don't understand where python314t.lib comes from. Or how to go about debugging/investigating this.

Sorry, but reading the report on GH like this is not possible. Would it be possible to attach a log file instead? TiA

Sorry I forgot to triple-quote it. But I can certainly also provide a text file.

Now it's more readable, no need for a text file!

Ah, that stupid generated header file again. If you define Py_GIL_DISABLED=0 (preprocessor) that should override it.

I think GitHub just use our old installer and so probably it's gotten mixed up with the builds again. Do we know whether build backends have learned to set the variable explicitly yet? If they have, I'll just pull out the attempt to generate headers, since it causes way more bugs than it solves.

Ah, that stupid generated header file again

Can we manually generate or fix a functioning header file? If not, would it be possible to release a new beta soon? Beta 1 is unfortunately unusable on Windows.

Manually removing #define Py_GIL_DISABLED 1 from pyconfig.h works for me.

If you define Py_GIL_DISABLED=0 (preprocessor) that should override it.

I tried that in mhammond/pywin32@aedcff9 and now even 3.13 fails: LINK : fatal error LNK1104: cannot open file 'python313t.lib'

https://github.com/mhammond/pywin32/actions/runs/14946775119/job/41991104423?pr=2605

Py_GIL_DISABLED has to be undefined in order not to link to python3t.lib:

cpython/PC/pyconfig.h.in

Lines 321 to 337 in 13c94d0

    
           #                       if defined(Py_GIL_DISABLED)

           #                       endif /* Py_GIL_DISABLED */

The line #define Py_GIL_DISABLED 1 is uncommented in the shipped pyconfig.h at:

cpython/PC/pyconfig.h.in

Lines 97 to 103 in 13c94d0

    
           /* Define to 1 if you want to disable the GIL */ 
        
           /* Uncomment the definition for free-threaded builds, or define it manually 
        
            * when compiling extension modules. Note that we test with #ifdef, so

           #ifndef Py_GIL_DISABLED 
        
           /* #define Py_GIL_DISABLED 1 */ 
        
           #endif

I'm facing the same issue that the linker tries to link the free-threading library on Windows.

This change led to a break in the JIT regen script, which @brandtbucher is looking at. I assume that's covered by a new issue and we can close this one.
