Old Synopsis: GCC does not enforce the left-most "const" in a  "const char * const"  declaration.

State-Changed-Why:
    Confirmed. This used to give an error with 2.95, but does
    no more. It is thus a regression. The code in question is
    -------------------------
    void foo(char *dest);
    
    int main() {
      const char * const p = "abc";
      foo (p);
    }
    ------------------------------
    The thing is weird, because if p is not initialized by 
    "abc" but with a null pointer, then gcc correctly gives
    an error...

    x.cc: In function `int main()':
    x.cc:5: passing `const char *const' as argument 1 of `foo(char *)' discards qualifiers
