my bad, NULL is defined in [0]:

"A pointer obtained by converting an integer constant expression with
the value 0, or such an expression cast to type void *, to a pointer
type; for example, (char *)0. The C language guarantees that a null
pointer compares unequal to a pointer to any object or function, so it
is used by many functions that return pointers to indicate an error."

Though, the issue of the precedence of the cast stays open.
