Not sure if you're reading too much into it, but this bug is currently
triggered by GetLastError() returning an error when in fact no error has
occurred.

The INVALID_SET_FILE_POINTER is the more conservative test, it seems to
me, and if SetFilePointer returns it, there *must* have been an error,
no?
