    Back in the day when it mattered, we did it like

    #define BV00		(1 <<  0)
#define BV01		(1 <<  1)
#define BV02		(1 <<  2)
#define BV03		(1 <<  3)
...etc

#define IS_SET(flag, bit)	((flag) & (bit))
#define SET_BIT(var, bit)	((var) |= (bit))
#define REMOVE_BIT(var, bit)	((var) &= ~(bit))
#define TOGGLE_BIT(var, bit)	((var) ^= (bit))

....then...
#define MY_FIRST_BOOLEAN BV00
SET_BIT(myFlags, MY_FIRST_BOOLEAN)
