No, what's invalid is that using an unadorned 0 is understood as a "null
pointer" by the compiler. That would happen in a lot of places except
on a variadic function.
However, the platform may define NULL as it wishes, and indeed in our
c.h it is defined (conditionally) as (void *)0. If the platform had
such a definition then it would work without issues.
I assume the platform in question does something like
#define NULL 0
which would be silly.
