--- Comment #4 from Andrew Burgess <andrew.burgess at embecosm dot com> --- I only suggested the alternative patch due to the issues you raised in comment #2. I agree with you that extending the test to cover darwin would be by far the better solution. I'm unable to test your proposed patch, but it certainly looks reasonable, and I like it more that my patch. For what it's worth I think that would be a good change to make. Thanks.
