The problem: how to declare a function that returns a function pointer:

	int (*foo)();
	foo = getfunc();

how to declare getfunc?

Well, let's see: if we call getfunc(), dereference the result,
and call that, we get an int.  In other words,

	(*getfunc())()

is an int, so we should say

	extern int (*getfunc())();

All clear?
