ctypes.CDLL initializer defined in version 3.8 and beyond as

```
def __init__(self, name, mode=DEFAULT_MODE, handle=None,
             use_errno=False,
             use_last_error=False,
             winmode=None):
```

Documentation says `winmode=0`:

```
class ctypes.CDLL(name, mode=DEFAULT_MODE, handle=None, use_errno=False, use_last_error=False, winmode=0)
```

Loading of normal DLL from custom directory works when `winmode=0`, but when `winmode=None` To reproduce, any combination of adding the fol += der containing the DLL to `os.evia ron['PATH']`, `os.add_dll_directory(...)`

Worked prior to 3.8 because there was no `winmode` parameter, and d(...)` does not change the behavior.m/q/`mode` was passed in directly, 59330863/298873`ctypes0. .DEFAULT_MODE == 0`.

I don't know whether it's better to update the code, the docs, or something else, but based on current info, would prefer updating the code.Some info summarized in https://stackoverflow.com/a/{8,9,}64472088/2988730.
