Bug report

Bug description:

There is bug into the declaration of a type for a pointer to function.
At this line there is this declaration:

Unfortunately, this declaration is wrong.
From this page:
https://learn.microsoft.com/en-us/windows/win32/api/processthreadsapi/nf-processthreadsapi-getthreaddescription
this is the correct declaration of the function:

HRESULT GetThreadDescription(
  [in]  HANDLE hThread,
  [out] PWSTR  *ppszThreadDescription
);

As you can see, the second parameter is PWSTR and not PCWSTR.
Next, into the code, GetThreadDescription() is called with the right types for the parameters and MSVC seems to tolerate this, but a more strict compiler like GCC does not.
However, this is very simple to fix with a tiny patch.

CPython versions tested on:

CPython main branch

Operating systems tested on:

Windows
