Will this still be my final result,using the official install packages available from the CYGWIN official internet packages hierarchy supplied with the latest installer's list? -- 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
