救命啊，编译一条程序，竟然得到这么多的警告???

[nobody_me]

我用vc6.0编译以下程序，得到警告.
#include <vector>
#include <iostream>
#include <string>
using namespace std;
main()
{
vector<string> a;
return 0;
}
得到下面这么多的警告，大家告诉我是怎么回事啊。

不用管它，在VC中用stl就是这样。

因为调试器支持的标识符最长是255个字符，超过了就会出现这个警告了
可以在前面加上这句话来避免
#pragma warning( disable : 4786)
