[cfe-dev] CXXBaseSpecifiers not returning same Type

[Reid Kleckner]

Clang has both sugared and concrete types.  By default, getting the type of
some AST node will give you information about the type as written.  In this
case, two different nested name specifiers were used, so there are two
different types.

If you want to compare types for equivalence, use the canonical types, or
simply use ASTContext::hasSameType(QualType, QualType).
