Right. '-mno-cygwin' is not a supported flag for gcc with version 4. It was there to allow a kind of cross compiler that targets Win32 instead of Cygwin. This is obviously not what you want anyway so it's of no consequence to you that the flag has been removed. :-) There are now actual cross compilers available in Cygwin for gcc 4 that serve the purpose of the old '-mno-cygwin' flag. -- 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
