extern "C" bug

["Norbert O. Stoeffler" <Norbert dot O dot Stoeffler at lpr dot e-technik dot tu-muenchen dot de>]

/*	The following code documents a bug or at least a very
	strange feature of the current versions of gcc-2.8 and egcs	*/

extern "C" {

/* 	according to C syntax the number of parameters to the following
   	function foo is not defined	*/

void					foo();

/* 	now we declare two function pointers, one global ... */

void					(*bar)();

/* 	... and one member of a structure with the same signature	*/

struct foo {
	void				(*bar)();
};

} // end of the extern "C" section


int main()
{
	// this call to "foo" conforms to the declartion
	foo(42);

	// the same is true for the call via function pointer "bar"
	bar(42);

	// but why is the pointer treated differently when part of a structure?????
	struct foo			f;

	f.bar(42); /* -> leads to an ERROR message:

	ernie_$ egcc ttt.C
	ttt.C: In function `int main()':
	ttt.C:35: too many arguments to function

	ernie_$ egcc --version
	egcs-2.91.60
	*/
}

It would be very helpful to me, to know if you consider this behaviour
as a bug and if it's going to be fixed sometimes. In practice it
complicates interfacing with old code, e.g. the RPC communication
mechanism. Thanks in advance.
