Proposed resolution (March, 2010):

  1. Change the definition of condition in 8.5 [stmt.select] paragraph 1 as follows:

      2. condition:
        expression
        attribute-specifieropt typedecl-specifier-seq declarator = initializer-clause
        attribute-specifieropt typedecl-specifier-seq declarator braced-init-list

  2. Insert the following text as a new paragraph at the end of 8.5 [stmt.select]:

    3. In the decl-specifier-seq of a condition, each decl-specifier shall be either a type-specifier or constexpr.

The grammar for condition in 8.5 [stmt.select] paragraph 1 does not allow for the constexpr specifier. This was not intended by the original proposal.
