Ok, C gurus of the world... is the following code portable and why or why
not? This code compiles and runs correct on gcc, Mac AUX cc, Ultrix cc,
and Mac MPW c. 

extern void printf;

main()
{
	void (*f)() = printf;

	f("Hello, world\n");		/* are these two methods equivalent? */
	(*f)("Hello, world again\n" );
}
