/* For the sake of symbolic names in gdb, define true and false as
enum constants. However, do not define _Bool as the enum type,
since the enum type might be compatible with unsigned int, whereas
_Bool must promote to int. */
_Bool must promote to int. Also, make _Bool a macro rather than a
typedef, to suppress warnings by the Sun Forte Developer 7 C
compiler that _Bool is a keyword in ISO C99. */
