And so it does:

---------------8<----------------
class Foo {
        struct Bar {
                public int a;
                public Bar (int a) { this.a = a; }
        }

        static void Main ()
        {
                object os = null;
                object oc = new System.Exception ();

                int i0 = 0;
                int i0d = new int ();

                int i1 = 1;

                Bar bs = new Bar ();
                Bar bc = new Bar (2);
                Bar ba; ba.a = 3;
        }
}
---------------8<----------------

produces the following warnings:

---------------8<----------------
foo22.cs(9,10): warning CS0219: The variable 'os' is assigned but its value is
never used
foo22.cs(12,7): warning CS0219: The variable 'i0' is assigned but its value is
never used
foo22.cs(13,7): warning CS0219: The variable 'i0d' is assigned but its value is
never used
foo22.cs(15,7): warning CS0219: The variable 'i1' is assigned but its value is
never used
foo22.cs(17,7): warning CS0219: The variable 'bs' is assigned but its value is
never used
---------------8<----------------

Note the absense of 'oc' and 'bc', which have non-trivial constructors.  I'm
not surprised that 'ba' isn't warned about, either -- it's too pedantic a case
for a warning like this.
