Proposed resolution (February, 2010):

In the grammar in 11.4 [class.mem], add the indicated production to the definition of member-declaration:

    member-declaration:
      decl-specifier-seqopt attribute-specifieropt member-declarator-listopt ;
      function-definition ;opt
      ::opt nested-name-specifier templateopt unqualified-id ;
      using-declaration
      static_assert-declaration
      template-declaration
      alias-declaration

The grammar for member-declaration in 11.4 [class.mem] does not include a production for the alias-declaration form of typedef declarations, meaning that something like

    struct S {
      using UINT = unsigned int;
    };

is ill-formed. This seems like an oversight.
