--- Comment #1 from Richard Smith <richard-llvm at metafoo.co.uk> ---
Why do you believe this is invalid? This code looks valid to me; it looks like
you found a GCC bug. EDG also accepts this code.

See [namespace.udecl]p19: "If a using-declaration uses the keyword typename and
specifies a dependent name, the name introduced by the using-declaration is
treated as a typedef-name."

Please reopen with an explanation if you still believe Clang is incorrect here.
