+ 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.
