In serveral of the utility sources (and once in Xlib) there is a definition of Bool:-
typedef enum _bool {FALSE, TRUE} Bool

Later on there are various places where you get:-
	Bool somevar;

	if(!somevar)...

Yet as far as I can recall ! is not defined to work over elements
enum's  it was only allowed due to over generous implementation of
enum's in PCC.  I was using a version of the compiler written from
scratch and it rejected everyone of these.  Using the more old
fashioned

typedef int Bool;
#define FALSE 0
#define TRUE 1

works just as well and is not a questionable construct.
