[Moved to DR at the November, 2014 meeting.]

Proposed resolution (September, 2013):

Change the second bullet of 6.6 [basic.link] paragraph 3 as follows:

• a non-volatile variable that is explicitly declared const or constexpr and of non-volatile const-qualified type that is neither explicitly declared extern nor previously declared to have external linkage; or

According to 6.6 [basic.link] paragraph 3,

A name having namespace scope (6.4.6 [basic.scope.namespace]) has internal linkage if it is the name of

• ...

• a non-volatile variable that is explicitly declared const or constexpr and neither explicitly declared extern nor previously declared to have external linkage; or

• ...

It would be more precise and less confusing if the phrase “explicitly declared const” were replaced by saying that its type is const-qualified. This change would also allow removal of the reference to constexpr, which was added by issue 1112 because constexpr variables are implicitly const-qualified but not covered by the “explicitly declared” phrasing.
