Hi i am doing C programming in netbeans and when i compile and run my program i get a message in the dos console that says i need to use the nodosfilewarning to disable the cygwin warning i am getting. I have attached a screenshot as it is a rather lengthy message to type out. I know that you have to put this variable into the batch file in C:/Cygwin/Cygwin.bat. It doesn't work though, maybe I am doing something wrong? Any guidance that you guys can offer would be much appreciated. Also, can you guys recommend me some good compilers other than bloodshed (dev c++) or MS visual studio that are free and are compatible with Windows Vista/7? Cheers.
