<pre>1. Source code (x.cpp):
namespace A { void f() { } }
namespace B { using namespace A; void g(); }
void B::g() { f(); }
2. Command line:
clang++ -c x.cpp
3. Output:
error: use of undeclared identifier 'f'; did you mean 'f'?
4. Notes:
This FEATURE(TM) was introduced somewhere in the revision range
(177716..178453] (at r177716, Clang compiles the code).
This is either a bug or a standard-conformant behavior change, but in the
latter case, diagnostics messages should be more explanatory: the compiler
should direct the user to 'A::f()'.</pre>
