I would just note that in the f08 draft (pp 281-282 of 08-007r2), the 
rules that require distinguishable specifics have been converted into 
Constraints.  Thus, while some lax compliers can argue conformance now, 
the new standard will require that they diagnose the error in the 
example code you posted.
