I believe these questions are the crux of your inquiry so I've stripped out the surrounding details. Apologies if you feel I've removed something you feel is a significant point. This goes to the heart of a difference between how Windows and Linux treat executables and various ingrained assumptions both make about their respective expectations (essentially what Adam said ;-) ). Cygwin does try to bridge this gap but it has its limits as well. This is actually not new issue and has been discussed many times in the past on this list. If you're interested in the details or, even better, in improving what's currently implemented, I'd recommend reviewing previous discussions, the ideas they generated, and the issues and limitations mentioned. That should help you understand the current state and provide you with an informed basis if you want to take a swing at providing some patch. The only short answer I can give you is that the current state is a compromise. That doesn't mean there isn't a better one. Just that it's a complicated area for many reasons so getting to a better state is also complicated. -- Larry _____________________________________________________________________ A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting annoying in email? -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
