C is intended to be low-level, like an extra fancy set of macros for writing assembly. It is intentionally not supposed to do that much for you because you need greater control to do things like writing UNIX. Nonetheless, if you use it seriously then you will find that gcc does outright refuse to compile a great many things that it recognizes as broken, rather than chugging along. There is no way to simply suppress all compiler errors because there should not be.

Nobody in this discussion has raised the possibility of writing web apps entirely in C and suppressing all compiler warnings as they did so. That is a scary idea. And it gets even scarier if we are advocating for newbies to start writing web apps that way.
