[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 typeinfo3;

typedef int int_t;

void main()

    /*int_t i;
    auto ti = typeid(typeof(i));
    printf("%s\n",ti.toString.ptr);
    assert(ti.toString() == "typeinfo3.int_t");
    assert(ti.next !is null);
    assert(ti.next.toString() == "int");
    assert(ti.init is null);*/
