typedef int T; struct S { typedef T T; };

faulted with 
  declaration of `typedef int S::T'
  changes meaning of `T' from `typedef int T'
but should be legal by 7.1.3.  Also faulted:

  typedef int T;
  struct S { typedef T Unused; typedef int T; };

not faulted if the typedef of Unused is removed.
