Is exception specification available?

#include <iostream>

#include <string>

using namespace std;

class c1

{

public:

     c1()

     {

        c1str = "error 1";

     }

     string c1str;

};

class c2

{

public:

     c2()

     {

        c2str = "error 2";

     }

     string c2str;

};

void fn() throw (c1,bad_exception)

{

     cout<<"have problem"<<endl;

     throw c2();

}

int main()

{

     try

     {

        fn();

     }

     catch (const c2 &err)

     {

        cout << err.c2str <<endl;

     }

     catch (const bad_exception &)

     {

         cout << "catch bad_exception"<<endl;

     }

     catch (...)

     {

         cout << "catch another exception"<<endl;

     }

     cout <<"Done"<<endl;

     return 0;

}

couldn't work well in VS 2005 as the books tell me,I tried DEV,It
couldn't work again.In the book(the C++ standard library)tell me,I
sould catch a bad_exception,why there were even no any exception throw?
