Beman, c'mon, this isn't fair! When we talked on the phone you said this
wasn't the problem you were seeing. We specifically discussed the .success
and .failure files, and IIRC you understood why they were still around. You
said the problem was that instead of skipping targets dependent on the
broken library, they were building anyway using an older version of the
.lib that was still hanging around. How can I expect to support your
testing requirements if you keep changing the story?
