Bug 374: malloc(0) and realloc(p,0) must not change errno on success   OPEN
http://austingroupbugs.net/view.php?id=374

Geoff had noticed an overlap between changes suggested in this open bug
and the changes needed to align with C17.

We also noted that glibc does not conform to the change we made in
2008-TC1 to require that errno is set to an implementation-defined
value if realloc(p,0) returns null.  This matches the change made in
C17 7.22.3.1 (overview) which says that if a null pointer is returned in
the size 0 case it is "to indicate an error".  However, 7.22.3.5 (realloc)
still says "If size is zero and memory for the new object is not
allocated, it is implementation-defined whether the old object is
deallocated" and "The realloc function returns a pointer to the new
object [...], or a null pointer if the new object has not been allocated"
which seems to imply a null pointer can be returned in this case without
it being considered an error.

Action: Eric to ask about this on the glibc mailing list.

Action: Nick to draft a Clarification Request to WG14.
