[LC++]ambiguity, temporaries, const

[Roberto Diaz]

Hi!

The following code shows that under gcc 2.95

		* Theres not ambiguity in f(P&) and f(const P&)
        * Temporaries passed by reference default to const &
        * Non-temporaries default to non-const

Is this g++ specificic? is there in the C++ standard?

#include <iostream>

using namespace std;

class P 
{
};

class A 
{
public:
  void f (P &p) { cout << "non-const" << endl; }
  void f (const P &p) { cout << "const" << endl; }
};

int 
main ()
{
  P p;
  A a;
  // why there is not ambiguity here? 
  a.f(p);
  // temporary not problems neither?
  a.f(P());
  return 0;
}

Thank you!
