Compatible types and argument type qualifiers

Compatible types and argument type qualifiers

Are the types of these two declarations compatible types?
void f(char *, char *);
void f(char *restrict, char *restrict);
or similarly:
void g(char *);
void g(char *const);
I'm having a hard time finding anything in the standard which covers the
issue. I'm mostly interested in the topic of whether it's valid to
manually prototype a function, omitting the restrict keyword, where the
actual type might have restrict-qualified arguments depending on the
version of C or version of other libraries in use.
