Is it true that const_cast is just a way to tell the compiler ‘stop moaning, treat this as a non-const pointer’? Are there any cases when const_cast itself is translated into actual machine code?

Conceivably,there could be architectures where a const pointer had a different representation to a non-const one, in which case the compiler would have to emit some code. I’m not aware of any such architectures, however.
