请教大大，一个C++编译错误，不知道咋回事

想做个数组队列，代码如下，在编译到定义队列
ACT_QUEUE g_que(0);
ACT_QUEUE z_que(1);
ACT_QUEUE c_que(2);

报错：
错误：expected identifier before numeric constant
错误：expected ‘,’ or ‘...’ before numeric constant
错误：expected identifier before numeric constant
错误：expected ‘,’ or ‘...’ before numeric constant
错误：expected identifier before numeric constant
错误：expected ‘,’ or ‘...’ before numeric constant

如果直接定义，不加参数，像这样，则不报这个错。
ACT_QUEUE g_que;
ACT_QUEUE z_que;
ACT_QUEUE c_que;

class QUE_ELEMENT

{

 public:

  int gz_flag;

  int level;

  int roleno;

  double liliang;



  vector < double > cg_liliang;



  QUE_ELEMENT(int v_gz_flag)

  {

    gz_flag = v_gz_flag;

    liliang = 0;

  

    if (v_gz_flag == 1)

      cg_liliang.resize(3,0);

  };





  QUE_ELEMENT & operator = (QUE_ELEMENT & vq);



};



class ACT_QUEUE

{

public:

   vector < QUE_ELEMENT > _que; 

   int head;

   int tail;



   boost::mutex q_mutex;



   ACT_QUEUE(int v_gz_flag)

   {

     _que.resize(LX_ACT_QUE_LEN,QUE_ELEMENT(v_gz_flag));

     head = tail = 0;

   };



   void init();

   bool push( const QUE_ELEMENT & vq);

   bool pop();
