namespace A { }
struct B {
  void f(A::nonexistent param);
  void* g(A::nonexistent param);
};

For f we get a much better error, but the ptr-declarator on g confuses things:

p.cc:3:13: error: ‘A::nonexistent’ has not been declared
   void f(A::nonexistent param);
             ^~~~~~~~~~~
p.cc:4:9: error: expected ‘;’ at end of member declaration
   void* g(A::nonexistent param);
         ^
p.cc:4:26: error: expected ‘)’ before ‘param’
   void* g(A::nonexistent param);
                          ^~~~~
