I have some code given to me by another person in which we have a structure

```
struct Pair {
    string s1;
    string s2;
    bool equivalent;
  };

```

Then he sets up a vector of these structs hard coded

```
std::vector<Pair> PairID;

  staticdata() {
      PairID={{"string","string2",true}, 
      {"string","string3",true}, 
      {"string","string4",false}, 
      {"string","string7",false}, 
      {"string3","string8",false}
    };
    }

```

Unfortunately my compiler is complaining on the line PairID={{"string","string2",true}, 

Why is this? He suggested to compile using -std=c++0x but my compiler (gcc 4.2) does not support this. Is there an easy way to convert the code so it works? Why is it failing??

I am using Mac OSX and would prefer not to update my compiler
