Annex D (Compatibility features) [C++03]
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
§7.3.1.1/2is present but striked out.
