No. C is a language with a specification independent of implementation. If you write correct C code (according to the specification, which no one does), it does not depend on any of those factors. C is almost uniquely bad in terms of accepting broken programs and just compiling them differently. But that doesn't change the fact that the language has semantics, even if most code that violates the documented preconditions those semantics depend on.
