Hum, I just checked and indeed there is a problem...

#define SUM_COUNTER(s,c)  do { (s).bcnt += (c).bcnt; (s).pcnt += (c).pcnt; } while(0)

need to be changed to use 

#define SUM_COUNTER(s, c)  do { xt_incr_counter(s, (c).cnt, (c).pcnt);} while (0)

Oops

#define SUM_COUNTER(s, c)  xt_incr_counter(s, (c).bcnt, (c).pcnt)
