* include/bits/cpp_type_traits.h: Changed __is_pod
completely. Now, it does not use any of the previous type_traits
to detect the pod types, and it also detects function pointers as
POD types.
* include/bits/stl_tree.h: Introduced a new class _Rb_tree_impl,
which encapsulates the internal implementation of an rb_tree. Made
the allocator a base class of this class instead of the rb_tree,
which was not conforming. This _Rb_tree_impl class is also
specialized on whether the _Compare parameter is a POD type or
not. If so, then it maintains the comparison function as a data
member, otherwise it makes the _Compare parameter a base class of
itself. Also, _M_key_compare is now a function instead of a data
member, so that the above trick can work properly. Delegated the
initialization of the other data members to this newly created
class. Also, now other member functions of rb_tree must refer to
_M_key_compare as _M_impl._M_key_compare(). The other data members
(*) can be referenced to as _M_impl.(*), where
(*) includes _M_header, and _M_node_count.

* include/bits/stl_list.h: Created a _List_impl class and made it
derive from the allocator, instead of the list deriving from the
allocator class, which was not conformant. Changed all references
from this->_M_node to this->_M_impl._M_node * bits/list.tcc: Same
as above (changed all references to the concerned variables).
2004-03-25 Dhruv Matani <dhruvbird@gmx.net>
* include/bits/stl_deque.h: Created a _Deque_impl class and made
it derive from the allocator, instead of the deque deriving from
the allocator class, which was not conformant. Changed all
references to the _M_start, _M_finish, _M_map, and _M_map_size to
_M_impl.*.
(_Deque_base<_Tp,_Alloc>::~_Deque_base()): Added this->
qualification in 2 places where it was missing.

above.

the concerned variables).

_M_impl.*.

* sem_attr.adb (Check_Dereference): When the prefix of a 'Tag
attribute reference does not denote a subtype, it can be any
expression that has a classwide type, potentially after an implicit
dereference. In particular, the prefix can be a view conversion for
a classwide type (for which Is_Object_Reference holds), but it can
also be a value conversion for an access-to-classwide type. In the
latter case, there is an implicit dereference, and the original node
for the prefix does not verify Is_Object_Reference.
* sem_util.adb (Is_Dependent_Component_Of_Mutable_Object): A view
conversion of a discriminant-dependent component of a mutable object
is one itself.
