It's totally nonsense to test on a native target. In that case you're
testing the operating system, not the fileio protocol, which is the
task of that test. Tweaking the testcase is even making things worse
since it's *strictly* defined how the fileio code works and what
return codes and error codes are expected. If you're going to weaken
the testcase by allowing different results just for the sake of running
a useless test, that's IMHO counterproductive.
