--- Comment #6 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
Another one, affecting C++ only:

void f() {
    printf("test");
}

<source>: In function 'void f()':
<source>:2:5: error: 'printf' was not declared in this scope
     printf("test");
     ^~~~~~
<source>:2:5: note: suggested alternative: 'int'
     printf("test");
     ^~~~~~
     int
