"-no-integrated-cpp This option allows a user supplied "cc1", "cc1plus", or "cc1obj" via the ‘-B’ option. The semantics of this option will change if "cc1", "cc1plus", and "cc1obj" are merged." What is cc1obj? is it preprocessor? and what is cc1plus? What does it mean when the document says: 'if "cc1", "cc1plus", and "cc1obj" are merged"?
