+ All this is quite ugly but serves two purposes:
+ 1. Be almost 100% compatible with old, untyped, wxList class
+ 2. Ensure compile-time type checking for the linked lists
-#ifdef __GNUG__
-#pragma interface "list.h"
-#endif
+ The idea is to have one base class (wxListBase) working with "void *" data,
+ but to hide these untyped functions - i.e. make them protected, so they
+ can only be used from derived classes which have inline member functions
+ working with right types. This achieves the 2nd goal. As for the first one,
+ we provide a special derivation of wxListBase called wxList which looks just
+ like the old class.

+ Note 2: the EmptyList is needed to allow having a NULL pointer-like
+ invalid iterator. We used to use just an uninitialized iterator object
+ instead but this fails with some debug/checked versions of STL, notably the
+ glibc version activated with _GLIBCXX_DEBUG, so we need to have a separate

+// -----------------------------------------------------------------------------
+
+// and now some heavy magic...
+
+// declare a list type named 'name' and containing elements of type 'T *'
+// (as a by product of macro expansion you also get wx##name##Node
+// wxNode-derived type)
+//
+// implementation details:
+// 1. We define _WX_LIST_ITEM_TYPE_##name typedef to save in it the item type
+// for the list of given type - this allows us to pass only the list name
+// to WX_DEFINE_LIST() even if it needs both the name and the type
+//
+// 2. We redefine all non-type-safe wxList functions with type-safe versions
+// which don't take any space (everything is inline), but bring compile
+// time error checking.
+//
+// 3. The macro which is usually used (WX_DECLARE_LIST) is defined in terms of
+// a more generic WX_DECLARE_LIST_2 macro which, in turn, uses the most
+// generic WX_DECLARE_LIST_3 one. The last macro adds a sometimes
+// interesting capability to store polymorphic objects in the list and is
+// particularly useful with, for example, "wxWindow *" list where the
+// wxWindowBase pointers are put into the list, but wxWindow pointers are
+// retrieved from it.
+//
+// 4. final hack is that WX_DECLARE_LIST_3 is defined in terms of
+// WX_DECLARE_LIST_4 to allow defining classes without operator->() as
+// it results in compiler warnings when this operator doesn't make sense
+// (i.e. stored elements are not pointers)
+
+// common part of WX_DECLARE_LIST_3 and WX_DECLARE_LIST_PTR_3
