@code{TYPE_PTRMEMFUNC_P} does not hold, this type is a class type. For
more information, see @pxref{Classes}.
@item UNKNOWN_TYPE
This node is used to represent a type the knowledge of which is
unsufficiant for a sound processing.
@item OFFSET_TYPE
This node is used to represent a data member; for example a
pointer-to-data-member is represented by a @code{POINTER_TYPE} whose
@code{TREE_TYPE} is an @code{OFFSET_TYPE}. For a data member @code{X::m}
the @code{TYPE_OFFSET_BASETYPE} is @code{X} and the @code{TREE_TYPE} is
the type of @code{m}.
@item TYPENAME_TYPE
Used to represent a construct of the form @code{typename T::A}. The
@code{TYPE_CONTEXT} is @code{T}; the @code{TYPE_NAME} is an
@code{IDENTIFIER_NODE} for @code{A}. If the type is specified via a
template-id, then @code{TYPENAME_TYPE_FULLNAME} yields a
@code{TEMPLATE_ID_EXPR}. The @code{TREE_TYPE} is non-@code{NULL} if the
node is implicitly generated in support for the implicit typename
extension; in which case the @code{TREE_TYPE} is a type node for the
base-class.
@item TYPEOF_TYPE
Used to represent the @code{__typeof__} extension. The
@code{TYPE_FIELDS} is the expression the type of which is being
represented.
@item UNION_TYPE
Used to represent @code{union} types. For more information, @pxref{Classes}.
