"Better off" == "it works" vs. "not better off" == "it doesn't work". >What surprised me was that the same shell, and same make, resulted in >different behaviour. I guess this is just reflecting differences in the >underlying process architectures of Linux vs Windows. Again, it *isn't* the same shell. You have now learned that it isn't the same shell and you now know that this is the reason for the inconsistency. ash isn't normally used as /bin/sh on linux. A stripped down version of ash is used as /bin/sh for performance purposes on cygwin. ash does not set PWD. 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/
