I am trying to get cygwin to work in command prompt on Vista. Specifically I want gnu for program compilation. I place this into my path in my system variables "C:\cygwin\bin". This works for XP, but maybe I'm just missing something. I have installed cygwin and no visible problems occurred during install. The main problem is that if I try to use the g++ or gcc commands in command prompt, it says "'g++' is not recognized as an internal or external command, operable program or batch file". I have also created a PATH in my user variables with the "C:\cygwin\bin", but it still does not work.
