diagnostic seen with g++-3.[234], not with g++-2.95

The program below doesn't compile. If you change "isalnum" in ptr_fun
to "isal", it compiles just fine, though.

#include <iostream>

using namespace std;
 
int isal(int c)
{
        return isalnum(c);
}
 
int main(int argc, char **argv)
{
        string component(argv[1]);
        if (find_if(component.begin(), component.end(),
                   ptr_fun(isalnum)) != component.end()) {
                cerr << "Error\n";
                return -1;
        }
}
