   Using G++ 1.35.0/Sun3, the following code gets the errors shown
   below the code.  If the definition of "function" is moved to a
   point *below* the declaration of the class "base", the errors
   go away.

   -----------------------------------------------------------------
   // Check that a global level function which has already been
   // either declared or defines may subsequently be declared
   // to also be a friend of some class.
   //
   // This generates an error in G++ 1.35.0


   int function (int i, int j)
   {
	   return i + j;
   }

   struct base {
	   int member;

	   friend int function (int, int);
   };

   int main ()
   {
	   return 0;
   }

   a036.C:9: after declaration of non-overloaded `int function (int, int)'
   a036.C:16: warning: `int function (int, int)' declared but never defined

There is a switch `NO_AUTO_OVERLOAD' which is presently #defined in
cplus-tree.h.  If you want C++ 2.0's automatic overloading of all
functions defined in C++ scope, comment out this #define.  It will
probably be commented out when 1.36.0 makes the scene.
