Using [static N] in an array parameter declaration also requires the
caller to pass a non-NULL pointer. If I want to tell the compiler
that an argument must not be a NULL pointer, I can write:
void func(int arg[static 1]);
func(NULL) then has undefined behavior, and a compiler is likely
to warn about it. (Of course some UB will be missed if the compiler
can't detect it.)
