+// 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_(F)FILE to 1 to compile wx(F)File classes. wxFile uses low level
+// POSIX functions for file access, wxFFile uses ANSI C stdio.h functions.
+//
+// Default is 1
+//
+// Recommended setting: 1 (wxFile is highly recommended as it is required by
+// i18n code, wxFileConfig and others)
+#define wxUSE_FILE 1
+#define wxUSE_FFILE 1
+
+// Use wxFSVolume class providing access to the configured/active mount points
+//
+// Default is 1

+#define wxUSE_FSVOLUME 1
+
+// use wxTextBuffer class: required by wxTextFile
+#define wxUSE_TEXTBUFFER 1
+
+// use wxTextFile class: requires wxFile and wxTextBuffer, required by
+// wxFileConfig
+#define wxUSE_TEXTFILE 1
+
+// i18n support: _() macro, wxLocale class. Requires wxTextFile.
+#define wxUSE_INTL 1
+
+// Set wxUSE_DATETIME 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
+//
+// Default is 1
+//
+// Recommended setting: 1
+#define wxUSE_DATETIME 1

+// Set wxUSE_TIMER to 1 to compile wxTimer class
+//
+// Default is 1

+//
+// Default is 1
+//
+// Recommended setting: 1 (needed by wxSocket)
+#define wxUSE_STOPWATCH 1
+
+// Setting wxUSE_CONFIG to 1 enables the use of wxConfig and related classes
+// which allow the application to store its settings in the persistent
+// storage. Setting this to 1 will also enable on-demand creation of the
+// global config object in wxApp.
+//
+// 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
+#define wxUSE_CONFIG_NATIVE 1
+
+// If wxUSE_DIALUP_MANAGER is 1, compile in wxDialUpManager class which allows
+// to connect/disconnect from the network and be notified whenever the dial-up
+// network connection is established/terminated. Requires wxUSE_DYNAMIC_LOADER.
+//
+// Default is 1.
+//
+// Recommended setting: 1
+#define wxUSE_DIALUP_MANAGER 1
+
+// Compile in classes for run-time DLL loading and function calling.
+// Required by wxUSE_DIALUP_MANAGER.
