[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.

extern(C) int printf(char*, ...);

class C

    }

void heap()
{
    auto c = new C;
    c.dump();
}

void stack()
{
    scope c = new C;
    c.dump();
}
