More accurately, "p == 0". Since 0 and NULL are both null pointer
constants, it shouldn't make any difference, but the actual wording used
by the standard corresponds to "p == 0".
Now implement
if ( p )
as not
if ( ( int ) p ) ; // !
Yes, that would be an incorrect way of implementing if(p) on such a
platform.
