The requirement is in (ANSI) 3.3.4 Cast Operators:

	A pointer may be converted to an integral type.  The size of
	integer required and the result are implementation-defined.  If
	the space provided is not long enough, the behavior is
	undefined.

My recollection of the discussion was that the committee agreed that
the result need not be sensible (e.g., a conforming implementation
could convert all pointers to 42) and that the implementation was free
to document that *no* integral type is long enough.
