I have the following program:

	extern int	printf(char*, ...);
	enum sym { FIRST, SECOND, THIRD };

	main()
	{
		void	func(int&);

		sym	foo = THIRD;
		int	far = 0;
		int&	boo = (int) foo;
		int&	bar = far;

		func(boo);
		printf("foo = %d, boo = %d\n", foo, boo);

		func(bar);
		printf("far = %d, bar = %d\n", far, bar);
	}

	void func(int& i)
	{
		i = 1;
		return;
	}

Why does Oasys C++ 1.2 yield

	foo = 2, boo = 1
	far = 1, bar = 1

I expected "foo = 1, boo = 1".  Do I misunderstand how references
work?

Thanks,
Mike Khaw
