Bug report

Trying to compile python 3.10.12 (as trying to compile 3.11.4, 3.12.0b2) on windows leads to following error:

  _testimportmultiple.vcxproj -> C:\Users\user\Documents\Projekte\cpython\PCbuild\amd64\_testimportmultiple.pyd
  _testmultiphase.c
     Bibliothek "C:\Users\user\Documents\Projekte\cpython\PCbuild\amd64\_testmultiphase.lib" und Objekt "C:\Users\user\Documents\Projekte\cpython\PCbuild\amd64\_testmultiphase.exp" werden erstellt.
  Code wird generiert.
  Codegenerierung ist abgeschlossen.
  _testmultiphase.vcxproj -> C:\Users\user\Documents\Projekte\cpython\PCbuild\amd64\_testmultiphase.pyd
  _testconsole.c
C:\Users\user\Documents\Projekte\cpython\PC\_testconsole.c(13,10): fatal  error C1083: Datei (Include) kann nicht geöffnet werden: "..\modules\_io\_iomodule.h": No such file or directory [C:\Users\user\Documents\Projekte\cpython\PCbuild\_testconsole.vcxproj]

Fehler beim Buildvorgang.

Renaming Modules to modules makes the error vanish, but leads to directory ..\Modules\... not found at other places.

Your environment

• Visual Studio 2022, 17.6.2

• Cygwin 3.5.x

• MSYS64

• Git 2.41.0_windows_1

• Python 3.10.11 or Python 3.11.4 (Python 3.12.0b1 is not usable -- to many errors).

• Windows 10 with file system partly case sensitive (not only case aware -- git configured to checkout to case sensitive file system and set case sensitivity -> git cloned parts of a file system are case sensitive this way. Directories with case only distinguished entries are possible).

• CPython versions tested on: 3.10.12

• Operating system and architecture: Windows 10, amd64, FS: NTFS
