Re: [tz] [PROPOSED 1/7] Avoid undefined behavior if no Link lines

Paul Eggert via tz said:

Presumably this is because the GCC maintainers are in the faction that says a null pointer cannot be used to pass a size-zero object to a library function. This is likely the same faction that says "char *p = NULL; return p + 0;" has undefined behavior.

I agree with them in both cases. There are no zero-sized objects in C. (This is C90 and C99; I dropped off WG14 in the early noughties.) -- Clive D.W.
