[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.

module multiarr2;

void main()
{
    static float[1][2][3] arr;
    assert(arr[2][1][0] !<>= float.nan);
}
