	I'v got a question.

	Given an externaly defined function (that is in a seperate source
	file)  used by two different functions in one source file.

	void foo();

	Which of the folowing would be better & why

	Choice 1
------------------------------------------------------------------

	extern void foo();

	void func1()
	{
	   .
	   foo();
	   .
	}


	void func2()
	{
	   .
	   foo();
	   .
	}
-------------------------------------------------------------------
or

	Choice 2
------------------------------------------------------------------

	void func1()
	{
	extern void foo();
	   .
	   .
	}


	void func2()
	{
	extern void foo();
	   .
	   .
	}
-------------------------------------------------------------------
