>Description:
According to Herb Sutter:
http://www.cuj.com/experts/2101/sutter.htm
The following two testcases are legal and should compile:

// Example 1 again
//
namespace boost {
  template<typename T> void checked_delete( T* x ) {
    // ... other stuff ...
    delete x;
  }
}
class Test {
  ~Test() { }
  friend void boost::checked_delete( Test* x ); // the original code
};

int main() {
  boost::checked_delete( new Test );
}

///////////////////////////////

// Example 2: The other way to declare friendship
//
namespace boost {
  template<typename T> void checked_delete( T* x ) {
    // ... other stuff ...
    delete x;
  }
}
class Test {
  ~Test() { }
  friend void boost::checked_delete<>( Test* x );
};

int main() {
  boost::checked_delete( new Test );
}

State-Changed-Why:
    Confirmed.
    
    This is probably a duplicate of PR 8355, but that report 
    seems so long and contrived that nobody seems to have taken
    the time yet to at least analyse it...
