c语言链表在不同编译器下的问题

明月

先贴代码
#include <stdio.h>
#include <stdlib.h>
struct pNode
{
        int data;
        struct pNode *pNext;
};
int main()
{
    int i;
    struct pNode *pHead=(struct pNode *)malloc(sizeof(struct pNode));
    struct pNode *pTail=pHead;
    //pTail=pHead;
    pTail->pNext=NULL;
        for(i=0;i<4;i++)
        {
                struct pNode *pNew=(struct pNode *)malloc(sizeof(struct pNode));
                pNew->data=i;
                pNew->pNext=NULL;
                pTail->pNext=pNew;
                pTail=pNew;
        }
        struct pNode *p=NULL;
        p=pHead->pNext;
        while(NULL!=p)
        {
                printf("%d\n",p->data);
                p=p->pNext;
        }
       
    return 0;
}

这段代码在VC++6.0下成功编译并得出了正确结果
但在Code::Blacks ＶＣ２０１０编译环境下却出现了很多错误

虽然不是什么大问题，但若有人知晓的还望多多指教一下～
