Defines
#define	BIN(x)
	because sdcc can't handle binary constats, they must be handled by this macro.
#define	bit_test(x, y)   ( x & (1<<y) )
	returns a positive value if bit y is set in byte x, 0 otherwise
#define	bit_clear(x, y)   ( x&= ~(1<<y) )
	clears bit y in byte x (sets it to 0)
#define	bit_set(x, y)   ( x|= (1<<y) )
	sets bit y in byte x (sets it to 1)
#define	bit_zeros(x)
	returns the number of 0-bits in the byte
#define	bit_ones(x)
	returns the number of 1-bits in the byte
#define	boolean   bool
	defines boolean as an alias for bool
