Declaration context for names declared as extern "C" in C++.
This is neither the semantic nor lexical context for such declarations, but is used to check for conflicts with other extern "C" declarations. Example:
The semantic context of #1 is namespace N and its lexical context is the LinkageSpecDecl; the semantic context of #2 is namespace N and its lexical context is the TU. However, both declarations are also visible in the extern "C" context.
The declaration at #3 finds it is a redeclaration of N::f
through lookup in the extern "C" context.
