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-seq_opt attribute-specifier_opt member-declarator-list_opt

;

function-definition

;

_opt

::

_opt

nested-name-specifier

template

_opt

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.
