The -Wchar-subscripts option doesn't seem to have any effect. IIRC,
it used to work at some point in the past but this test case doesn't
seem to trigger it in any compiler between 2.95 and 3.4 regardless
of whether char is signed or unsigned.

$ cat t.cpp && g++ --version && g++ -Wchar-subscripts t.cpp
char foo (const char *s)
{
    return s [s ['\x80']];
}

int main ()
{
    foo ("\x80");
}
