From include/parrot/parrot.h:
/* weird architectures might need this, s. C-FAQ 5.17
*
* the SET_NULL macros are only for system, where a NULL pointer
* isn't represented by zeroes, so don't use these, for resetting
* non-null pointers
*/
#ifdef HAS_NON_ZERO_NULL
# define SET_NULL(x) x = NULL
# define SET_NULL_P(x, s) x = (s)NULL
#else
# define SET_NULL(x)
# define SET_NULL_P(x, s)
#endif /* HAS_NON_ZERO_NULL */
This seems very wrong. SET_NULL() isn't actually setting any values
if not HAS_NON_ZERO_NULL. Is there some reason it's not actually
# define SET_NULL(x) x = 0
# define SET_NULL_P(x, s) x = (s)NULL
And for that matter, what's wrong with just using x = NULL
everywhere? Why do we need a macro to do this?

Andy
