You are right, it depends, whether you write C (from the standard) or a specific dialect from your vendor (everybody does in practice). In the latter case, you need to know about the rules of the compiler. But to allow optimization, these are often similar, so that the compiler assumes these have the behaviour of the implementation, that the compiler is tailored against.
