My Java native components are usually compiled under Visual C++.

This is why I went for 'Cygwin', but 'Cygwin', and especially the 'Cygwin' DLL, isn't required for my components to work. -- Claude SIMON http://zeusw.org/ -- 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
