[Ignore my previous followup.  I accidentally posted it before I
finished writing it.]

There are three scenarios being considered.

1. malloc(0) always returns a null pointer.
2. All malloc(0) calls return the same non-null pointer, perhaps to a
   single pre-allocated object.
   3. malloc(0) acts like malloc(1), returning a null pointer only if
      memory has been exhausted.

Implementations currently choose between 1 and 3; 2 would be
non-conforming.  Kaz suggested allowing (or requiring?) 2.  (I advocate
requiring 3, which is the current behavior of all the implementations
I've tried.)

Tim is talking about scenario 2.  Your code sample would work correctly
in that scenario.
