I have always been under the impression that a CHAR variable and an INT variable
were the same in 'C'- yet I now see:

In the sequence:

	main()
	{
		char c = 'w';
		foo(c)
	}

	foo(ch)
	char ch;

char ch is the correct declaration.  The compiler/code generator should
handle pulling the character portion of the promoted variable off the
stack correctly.  Declaring it 'int' is asking for trouble.

Why is it asking for trouble to declare ch as INT when K&R says they are the
same?
