// RUN: clang-cc -fsyntax-only -verify %s
// This test concerns the identity of dependent types within the
// canonical type system, specifically focusing on the difference
// between members of the current instantiation and membmers of an
// unknown specialization. This considers C++ [temp.type], which
// specifies type equivalence within a template, and C++0x
// [temp.dep.type], which defines what it means to be a member of the
// current instantiation.
