I can compile this code by borland compiler.
What is the reason that i get "compilation error" there?

<code>
#include <iostream>
#include <vector>
#include <algorithm>

using namespace std;

int main(void){
  vector<string> v;
  v.push_back("abcd");
  v.push_back("abce");
  next_permutation(v.begin(), v.end());
  return 0;
}
<\code>
