Protected and public symbols are, but a protected symbol is guaranteed to reference the declared object within a library - a public symbol means that all references to that symbol eventually resolve to the same symbol, regardless of which library the came from. For the most part, UNIX dynamic symbols are public, and Windows ones are protected. n2425 does not define any other semantics though, such as specifying linked libraries. --- [ comp.std.c++ is moderated.
