+// 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.
+//
+// Recommended setting: 0
+#define wxICON_IS_BITMAP 0

+// Set wxUSE_LONGLONG to 1 to compile the wxLongLong class. This is a 64 bit
+// integer which is implemented in terms of native 64 bit integers if any or
+// uses emulation otherwise.
+//
+// This class is required by wxDateTime and so you should enable it if you want
+// to use wxDateTime. For most modern platforms, it will use the native 64 bit
+// integers in which case (almost) all of its functions are inline and it
+// almost does not take any space, so there should be no reason to switch it
+// off.
+//
+// Recommended setting: 1
+#define wxUSE_LONGLONG 1
+
+// Set wxUSE_TIMEDATE to 1 to compile the wxDateTime and related classes which
+// allow to manipulate dates, times and time intervals. wxDateTime replaces the
+// old wxTime and wxDate classes which are still provided for backwards
+// compatibility (and implemented in terms of wxDateTime).
+//
+// Note that this class is relatively new and is still officially in alpha
+// stage because some features are not yet (fully) implemented. It is already
+// quite useful though and should only be disabled if you are aiming at
+// absolutely minimal version of the library.
+//
+// Requires: wxUSE_LONGLONG

+// Setting wxUSE_CONFIG to 1 enables the use of wxConfig and related classes
+// which allow the application to store its settings in the persistent

+//
+// See also wxUSE_CONFIG_NATIVE below.
+//
+// Recommended setting: 1
+#define wxUSE_CONFIG 1
+
+// If wxUSE_CONFIG is 1, you may choose to use either the native config
+// classes under Windows (using .INI files under Win16 and the registry under
+// Win32) or the portable text file format used by the config classes under
+// Unix.
+//
+// Default is 1 to use native classes. Note that you may still use
+// wxFileConfig even if you set this to 1 - just the config object created by
+// default for the applications needs will be a wxRegConfig or wxIniConfig and
+// not wxFileConfig.
+//
+// Recommended setting: 1

+
+// If wxUSE_DIALUP_MANAGER is 1, compile in wxDialUpManager class which allows

+// class may be compiled in if wxUSE_TOOLBAR_SIMPLE is 1.
