Proposed resolution (September, 2009):

Change 7.7 [expr.const] paragraph 2, bullet 4, sub-bullet 1 as indicated:

  • an lvalue-to-rvalue conversion (7.3.2 [conv.lval]) unless it is applied to

    • an lvalue of effective integral or enumeration type that refers to a non-volatile const variable or static data member initialized with constant expressions, or

    • ...

According to 7.7 [expr.const] paragraph 2, bullet 4, sub-bullet 1, a non-volatile const variable or static data member initialized with constant expressions can be used in an integral constant expression only if it is “of effective integral type.” Unscoped enumeration types should also be accepted in such contexts.
