+ 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:
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.
