>Description:
	ISO C++ Standard clause 8.3.6 Default arguments says:
	A default argument shall not be redefined by a later declaration (not even to the same value).

	The g++ compiler allows a later declaration to the same value.

>How-To-Repeat:

SOURCE CODE "foo.cc"

#include <iostream>

void foo(int, int = 0);
void foo(int, int = 0);

void foo(int a, int b)
{
	std::cout << a << std::endl;
	std::cout << b << std::endl;
}

main()
{
	foo(1, 2);
	foo(3);
}
