+// in wxMSW version 2.1.11 and earlier, wxIcon always derives from wxBitmap,
+// but this is very dangerous because you can mistakenly pass an icon instead
+// of a bitmap to a function taking "const wxBitmap&" - which will *not* work
+// because an icon is not a valid bitmap
+//
+// Starting from 2.1.12, you have the choice under this backwards compatible
+// behaviour (your code will still compile, but probably won't behave as
+// expected!) and not deriving wxIcon class from wxBitmap, but providing a
+// conversion ctor wxBitmap(const wxIcon&) instead.

+
+// Generic comment about debugging settings: they are very useful if you don't
+// use any other memory leak detection tools such as Purify/BoundsChecker, but
+// are probably redundant otherwise. Also, Visual C++ CRT has the same features
+// as wxWindows memory debugging subsystem built in since version 5.0 and you
+// may prefer to use it instead of built in memory debugging code because it is
+// faster and more fool proof.
+//
+// Using VC++ CRT memory debugging is enabled by default in debug mode
+// (__WXDEBUG__) if wxUSE_GLOBAL_MEMORY_OPERATORS is *not* enabled (i.e. is 0)
+// and if __NO_VC_CRTDBG__ is not defined.
+
+// If 1, enables wxDebugContext, for writing error messages to file, etc. If
+// __WXDEBUG__ is not defined, will still use normal memory operators. It's
+// recommended to set this to 1, since you may well need to output an error log
+// in a production version (or non-debugging beta).
+//
+// Default is 1.
+//
+// Recommended setting: 1 but see comment above
+#define wxUSE_DEBUG_CONTEXT 1
+
+// If 1, enables debugging versions of wxObject::new and wxObject::delete *IF*
+// __WXDEBUG__ is also defined.
+//
+// WARNING: this code may not work with all architectures, especially if
+// alignment is an issue. This switch is currently ignored for mingw / cygwin
