Wow, nice catch. I'm not in a position to actually test this right now but it seems like there was an obvious bug in the symlink code which I think I've fixed. I'm building a snapshot now. If you are in a position of being able to test this when it finally shows up I'd appreciate hearing if my changes fixes the problem. cgf -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
