The standard says  (refering to allocation routines)

	If the size of the space requested is zero, the behavior
	is implementation-defined; the value returned shall be
	either a null pointer or a unique pointer.

I have always read "unique pointer" as meaning different from
previously allocated pointers including pointers previously
returned by malloc(0).  However I have just been talking to
some people who insist it means that the same pointer is returned
on each call of malloc(0).

Comments?
