static keyword useless in namespace scope?

Question

namespace N
{
   static int x = 5;
}

What could be the importance/use-cases of declaring having a static variable at namespace scope?

Answer 1

Annex D (Compatibility features) [C++03]

D2: The use of the static keyword is deprecated when declaring objects in namespace scope.

Use unnamed namespaces instead as mentioned in this post.

static keyword imparts internal linkage to variables/objects in C as well as in C++ in namespace scope as others have mentioned in their posts.

P.S: Thie feature has been undeprecated as per the latest draft (n3290). In n3225 §7.3.1.1/2 is present but striked out.
