<pre>This diagnostic inconsistency has been discovered while
updating the following Lit test for C++11 compatibiliity.
CXX/dcl.dcl/basic.namespace/namespace.udecl/p4.cpp
Here is a reduced test case:
/***********************************/
struct Base { };
struct C : Base {
int bar();
using C::bar;
};
/***********************************/
When compiling in C++98, Clang issues both an Error and a Note.
$ clang useself.cpp -c -std=c++98 -Wall -Weverything
useself.cpp:7:12: error: using declaration refers to its own class
using C::bar;
~~~^
useself.cpp:6:7: note: target of using declaration
int bar();
^
1 error generated.
When compiling in C++11, Clang issues just an Error.
$ clang useself.cpp -c -std=c++11 -Wall -Weverything
useself.cpp:7:12: error: using declaration refers to its own class
using C::bar;
~~~^
1 error generated.</pre>
