 Actually it's defined as following in <sys/cdefs.h>:

 /*
  * To be used when an empty body is required like:
  *
  * #ifdef DEBUG
  * # define dprintf(a) printf(a)
  * #else
  * # define dprintf(a) __nothing
  * #endif
  *
  * We use ((void)0) instead of do {} while (0) so that it
  * works on , expressions.
  */
 #define __nothing	(/*LINTED*/(void)0)
