Hello, folks.
I am attempting to build a python binary wheel for protobuf from the PyPi
4.25.3 source wheel <https://pypi.org/project/protobuf/4.25.3/#files> under
github actions, in this workflow. The builds broke due to missing
identifiers under python/identifier.c:
```
C:\Users\runneradmin\AppData\Local\Temp\cibw-sdist-m44pjj69\protobuf-4.25.3\upb/message/internal/array.h(123):
warning C4334: '<<': result of 32-bit shift implicitly converted to 64 bits
(was 64-bit shift intended?)
C:\Users\runneradmin\AppData\Local\Temp\cibw-sdist-m44pjj69\protobuf-4.25.3\upb/message/accessors.h(316):
warning C4267: 'function': conversion from 'size_t' to 'int', possible loss
of data
python\descriptor.c(48): error C2059: syntax error: ';'
python\descriptor.c(53): error C2059: syntax error: '}'
python\descriptor.c(56): error C2065: 'PyUpb_DescriptorBase':
undeclared identifier
python\descriptor.c(56): error C2065: 'base': undeclared identifier
```
Is there any specific procedure for building windows from source, or any
assumptions about the environment that should be respected? I ran out of
ideas on how to troubleshoot this, any help is welcome.
Python version: 3.9.13
Github actions image: windows-2022
