Error with g++ of gcc3.1 (urgently need help)

["Tony, Zhou Jingtao" <zhoujing at figaro dot ddns dot comp dot nus dot edu dot sg>]

Dear GCC team,

I've got confused about the error gcc3.1 gives me. Please do help.

I have a simple c++ program that can compile successfully with the g++ of gcc3.0.4:

#include <iostream>
#include <fstream>
#include <string>

using namespace std;

int main(){
   ifstream inFile("cintest.in");
   string line;

   while (getline(inFile, line)){
      cout << line << endl;
   }

   inFile.close();

   return 0;
}


Nevertheless, when I upgraded it to gcc3.1, and tried compiling it again with g++, it gives me the following errors:
