I agree that the code is wrong.  However, one of those is an alias and 
the other is a typedef.  I suppose it could be debated which is which, 
but only one is a typedef.

I think that the error messages are good, even if they aren't perfect. 
My point is that those four pieces of code are essentially the same but 
all four produce different error messages.  Could they all be made the same?
