-by category (and sorted by alphabetical order inside each category).
-All of these macros except for the @c wxUSE_XXX variety is defined if the
-corresponding condition is @true and undefined if it isn't, so they should be
-always tested using @ifdef_ and not @if_.

@c 5.0, @c 1200 for @c 6.0 and so on. For convenience, the symbols

Some library features may not be always available even if they were selected
by the user. To make it possible to check if this is the case, the library
Currently the following symbols exist:
@beginDefList
+@itemdef{wxHAS_3STATE_CHECKBOX, Defined if wxCheckBox supports wxCHK_3STATE
+ flag, i.e. is capable of showing three states and not only the usual two.
+ Currently defined for almost all ports.}
@itemdef{wxHAS_ATOMIC_OPS, Defined if wxAtomicInc() and wxAtomicDec() functions
have an efficient (CPU-specific) implementation. Notice that the functions
themselves are always available but can be prohibitively slow to use when
implemented in a generic way, using a critical section.}
+@itemdef{wxHAS_BITMAPTOGGLEBUTTON, Defined in @c wx/tglbtn.h if
+ wxBitmapToggleButton class is available in addition to wxToggleButton.}
@itemdef{wxHAS_CONFIG_TEMPLATE_RW, Defined if the currently used compiler
supports template Read() and Write() methods in wxConfig.}
-@itemdef{wxHAS_LARGE_FILES, Defined if wxFile supports files more than 4GB in size.}
-@itemdef{wxHAS_LARGE_FFILES, Defined if wxFFile supports files more than 4GB in size.}
+@itemdef{wxHAS_LARGE_FILES, Defined if wxFile supports files more than 4GB in
+ size (notice that you must include @c wx/filefn.h before testing for this
+ symbol).}
+@itemdef{wxHAS_LARGE_FFILES, Defined if wxFFile supports files more than 4GB in
+ size (notice that you must include @c wx/filefn.h before testing for this
+ symbol).}
+@itemdef{wxHAS_LONG_LONG_T_DIFFERENT_FROM_LONG, Defined if compiler supports a
+ 64 bit integer type (available as @c wxLongLong_t) and this type is
+ different from long. Notice that, provided wxUSE_LONGLONG is not turned
+ off, some 64 bit type is always available to wxWidgets programs and this
+ symbol only indicates a presence of such primitive type. It is useful to
+ decide whether some function should be overloaded for both
+ <code>long</code> and <code>long long</code> types.}
@itemdef{wxHAS_MULTIPLE_FILEDLG_FILTERS, Defined if wxFileDialog supports multiple ('|'-separated) filters.}
+@itemdef{wxHAS_IMAGES_IN_RESOURCES, Defined if <a href="http://en.wikipedia.org/wiki/Resource_(Windows)">
+ Windows resource files</a> or OS/2 resource files are available on the current platform.}
@itemdef{wxHAS_POWER_EVENTS, Defined if wxPowerEvent are ever generated on the current platform.}
@itemdef{wxHAS_RADIO_MENU_ITEMS,
Defined if the current port supports radio menu items (see wxMenu::AppendRadioItem).}

Microsoft Visual C++ users may use the special @c wx/setup.h file for this
compiler in @c include/msvc subdirectory. This file implicitly links in all the
desirable, for example because some of them were not built and this is where
the symbols in this section can be helpful: defining them allows to not link
with the corresponding library. The following symbols are honoured:

- wxNO_AUI_LIB
