[求助] ucosii移植的问题

我学习ucosii,试图把ucosii移植到51单片机上。

INT8U         OSTaskCreate            (void           (*task)(void *p_arg),

sbit P11 =P1^1;

INT8U data task1stk[stksize];
INT8U idata task2stk[stksize];

void max(void)reentrant ;


void task1(void);
void task2(void);

void main(void)
{
	Time_Init ();
	OSInit();
	OSTaskCreate(task1,(void* )0,task1stk,task1prio);
	//OSTaskCreate(task1,(void * )0,&task1stk[stksize-1],2);
	OSTaskCreate(task2,(void * )0,task2stk,task2prio);
	OSStart();
	

}

void task1(void) 
{


while(1)
	
{
	P10 = !P10;
	//max();
	OSTimeDlyHMSM(0,0,1,0);

}

}

void task2(void) 
{

while(1)
	
{
	
	P11 = !P11;
	OSTimeDlyHMSM(0,0,2,0);

}

}

void max(void)reentrant
{
 INT32U i;
	i++;

}

可是编译有两个不对劲的警告

产生警告的语句如下：

OSTaskCreate(task1,(void* )0,task1stk,task1prio);
	//OSTaskCreate(task1,(void * )0,&task1stk[stksize-1],2);
	OSTaskCreate(task2,(void * )0,task2stk,task2prio);

请问高手，哪里出了问题？如何解决？谢谢！
