[Bug c++/33003] New: missed diagnostic about unused variable.

[pluto at agmk dot net]

class X
{
    public:
        static X& instance();
        static void init();
    private:
        X();
};

void f()
{
    X& x = X::instance();
    x.init();
}

in this case the 'x' variable is initialized and unused.
gcc-4.2 accepts this w/o any warning at -Wall -Wextra
but vs2005-express reports warning C4189 at warning level 4.
