/*
  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

  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 1: the outer helper class _WX_LIST_HELPER_##liT below is a workaround
    for mingw 3.2.3 compiler bug that prevents a static function of liT class
    from being exported into dll. A minimal code snippet reproducing the bug:

         struct WXDLLIMPEXP_CORE Foo
         {
            static void Bar();
            struct SomeInnerClass
            {
              friend class Foo; // comment this out to make it link
            };
            ~Foo()
            {
                Bar();
            }
         };

    The program does not link under mingw_gcc 3.2.3 producing undefined
    reference to Foo::Bar() function


    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
    invalid iterator.

// -----------------------------------------------------------------------------
// macros for definition of "template" list type
// -----------------------------------------------------------------------------

// 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)
