I don't think G++ supports that.
You can do it using the TR1 library extensions:
#include <tr1/functional>
struct A
{
int f();
};
int main()
{
using std::tr1::function;
using std::tr1::bind;
A a;
function<int()> f = bind(&A::f, a);
return f();
}
The same functionality is available in the Boost library too.
