What the OP meant is that there are (multiple!) open source C compilers, which you agree is the case. Questions about the standard/specification are a different matter: 1. Whether the language has one? (Many languages, both open source and proprietary don't! I believe mojo doesn't have one?) 2. Whether it's available for free (gratis)? 3. Whether it's under a free (libre) license that allows redistribution with modifications?
