It would be great and sufficient if the stub returned the corresponding error
code instead of crashing.

I'll look at the Wine source code for NtExtendSection().

No, there is no such Win32/Win64 API. According to the official documentation,
Windows can't do this.

Is enough to just return STATUS_NOT_IMPLEMENTED ((NTSTATUS)0xC0000002L) instead
of crash.
