libstdc++/6532: STL binder1st::operator() not compiling

[Paolo Carlini]

Hi,

your analysis is essentially correct. This is a limitation of the 
standard binders... Boost (www.boost.org) to the rescue! Why don't 
consider using boost::bind? Like this:

#include <algorithm>
#include <functional>
#include <boost/bind.hpp>

using namespace std;
using namespace boost;

struct A {
  int _a;
};

struct B {
  void m(A &x) { x._a = 5; }
  void f();
};

void B::f()
{
  A a[5];
  for_each(&a[0], &a[5], bind(&B::m, ref(this), _1));
}

Ciao,
Paolo.
