Missing implicitly declared member functions

[Valentin Bonnard]

[ Perhaps it's a known limitation. ]

Given

    struct T { };

T should have 6 member functions implicitly declared by 
the compiler.

But two of them are missing in egcs:

struct T
{ 
  // T* operator& () { return this; }
};

int main ()
{
  T* (T::*a) () = &T::operator&; // ERROR
  const T* (T::*b) () const = &T::operator&; // ERROR
  T& (T::*c) (const T&) = &T::operator=; // OK
  T x;
  if (0)
    x.~T (); // OK
}

Both & are missing. If I uncomment the declaration 
of operator&, then the program compiles ! This is 
strange because I have only written one & and I use 
both.
