[svn r231] Changed: warnings are no longer treated as an error. Added some comments and cleaned up CallExp::toElem a tiny bit. Fixed: struct literals always reported inplace assignment even if they allocated a temporary. Fixed: passing stuff to a D-style vararg which did inplace assignment was generated suboptimal code.

class Foo
{
    this(int j)
    {
        i = pi = j;
    }

    int i;

private:

    int pi;
}

class Bar : Foo
{
    this(int j)
    {
        super(j);
        baz = 42;
    }

    int baz;
}

void func()
{
    auto bar = new Bar(12);
}

void main()
{
    func();
}
