[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.
