[Moved to DR at the April, 2013 meeting.]

Proposed resolution (October, 2012):

Delete 9.2.2 [dcl.stc] paragraph 7:

A name declared in a namespace scope without a storage-class-specifier has external linkage unless it has internal linkage because of a previous declaration and provided it is not declared const. Objects declared const and not explicitly declared extern have internal linkage.

There is a contradiction in the specification of the linkage of members of the unnamed namespace, for example

  namespace {
    int x;
  }

According to 6.6 [basic.link] paragraph 4,

An unnamed namespace or a namespace declared directly or indirectly within an unnamed namespace has internal linkage. All other namespaces have external linkage. A name having namespace scope that has not been given internal linkage above has the same linkage as the enclosing namespace if it is the name of

• a variable; or

• ...

which would give x internal linkage. However, 9.2.2 [dcl.stc] paragraph 7 says,

A name declared in a namespace scope without a storage-class-specifier has external linkage unless it has internal linkage because of a previous declaration and provided it is not declared const.

This would give x external linkage. (This appears to have been a missed edit from the resolution of issue 1113.)
