[Bug c++/41825] New: useless -Wshadow warning on function argument in local class

["msebor at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

The warning on the code below isn't useful since the formal argument of foo()
named i cannot be referenced in the body of the local struct. I.e., there is
no potential for referring to it by mistake since doing so would be a hard
error.

$ cat t.cpp && g++ -c -Wshadow t.cpp
int foo (int i)
{
    struct {
        int bar (int i) { return i; }
    } s;

    return s.bar (i);
};
t.cpp: In member function ?int foo(int)::<anonymous struct>::bar(int)?:
t.cpp:4: warning: declaration of ?int i? shadows a parameter
t.cpp:1: warning: shadowed declaration is here
