erroe C141 and c202

my program is this:

#include <REGX51.h>
#include <math.h>

#define s_pin P2^0;
#define w_sensor P2^7;
#define red_led P3^0;
#define yellow_led P3^1;
#define buzr P1^0;

main() { while(1) { if(s_pin==0 & w_sensor==1) { SET yellow_led; CLR red_led; } else if(switch_pin==1) { SET red_led; CLR yellow_led; SET buzr; }

} }

and error are these:
