(A) You misunderstood the point I was making (as Keith's
followups more or less explained).

(B) Handling both implementation choices is trivial:
    employees = malloc(Nemployees * sizeof(EMPLOYEE));
    if (!employees && Nemployees)
       goto out_of_memory;

(C) Alternatively, it is quite straightforward to write
a wrapper to malloc() and free() that returns a non-null
pointer for a size of zero (and that is a lower cost
path in terms of cycles used and memory resources needed
than the behavior implementations are required to provide
if they return a non-null pointer).

(D) The code you suggest is "natural" for people who are
lazy programmers who don't care about their code being
correct.  There are easy ways around the deficiencies
of your example and any competent developer will use them.
