problem in using bind2nd in gcc 3.0.4

[Srinivasan Vaikundaramanujam <svaikund at cisco dot com>]

Hi All,
    I have a following code which is giving the cryptic compilation
error as it is already declared in `std::binder2nd<MyEquals>'.
Any pointers on this will be really helpful.

#include <iostream>
#include <functional>

#include <vector>
using namespace std;
struct MyEquals : public binary_function <const int,const int, bool>
{
        bool operator()(const int c, const int i) const
        {
                return(c == i);
        }
};
int main()
{
vector<int> v1;
v1.push_back(1);
v1.push_back(2);
v1.push_back(3);
v1.push_back(4);
vector<int>::iterator pos = find_if( v1.begin(), v1.end(),
bind2nd(MyEquals(),2));
cout << *pos << endl;
return 0;
}
