Confirmed, with --path it is possible to convert the Windows PATH to a cygwin PATH, that then gets converted to a Windows PATH again when invoking a Windows program. One binary call is obviously much faster than iterating every element in PATH and converting them one by one, which makes it a viable solution. -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation: https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
