[Bug c++/13947] New: ptr_fun doesn't recognise argument

[forwarded from http://bugs.debian.org/222497]

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>
#include <string>
#include <algorithm>
#include <functional>
#include <cctype>
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;
        }
}

This is a dup of bug 5458.  (even though their testcases are different, I can reduce it to the same 
problem).

*** This bug has been marked as a duplicate of 5458 ***
