No, the prototype should never use const for stack arguments (pointer to
const is totally different and should be used anywhere that it is correct).

I don't know any responsible libraries that const-ify value parameters in
prototypes. I think it most commonly arises from ignorance of, or sloppiness
with, the actual semantics of the C language.
