??  The DR you refer to deprecates realloc(p, 0), not realloc(0, p).
The latter is used much more widely, e.g. by not special casing
the first allocation.  So you use
  void *p = NULL;
  for (...)
    {
      void *q = realloc (p, sz);
      if (q == NULL)
        whatever;
      p = q;
      ...
    }
