+\section{Preprocessor symbols defined by wxWidgets}\label{cppconst}
These are preprocessor symbols used in the wxWidgets source, grouped
by category (and sorted by alphabetical order inside each category). All of
\twocolitem{\_\_WINDOWS\_\_}{any Windows, yom may also use \_\_WXMSW\_\_}
\twocolitem{\_\_WIN16\_\_}{Win16 API (not supported since wxWidgets 2.6)}
\twocolitem{\_\_WIN32\_\_}{Win32 API}
-\twocolitem{\_\_WIN95\_\_}{Windows 95 or NT 4.0 and above system (not NT 3.5x)}
\twocolitem{\_\_WXBASE\_\_}{Only wxBase, no GUI features (same as \texttt{wxUSE\_GUI} $== 0$)}
\twocolitem{\_\_WXCOCOA\_\_}{OS X using Cocoa API}
\twocolitem{\_\_WXWINCE\_\_}{Windows CE}
\twocolitem{\_\_WXMGL\_\_}{SciTech Soft MGL (\_\_WXUNIVERSAL\_\_ will be also
defined)}
\twocolitem{\_\_WXMSW\_\_}{Any Windows}
-\twocolitem{\_\_WXOS2\_\_}{Identical to \_\_WXPM\_\_}
\twocolitem{\_\_WXOSX\_\_}{Any Mac OS X port (either Carbon or Cocoa)}
\twocolitem{\_\_WXPALMOS\_\_}{PalmOS}
\twocolitem{\_\_WXPM\_\_}{OS/2 native Presentation Manager}
\begin{itemize}
\item If you want to test for all Mac platforms, classic and OS X, you
should test both \texttt{\_\_WXMAC\_\_} and \texttt{\_\_WXCOCOA\_\_}.
-\item If you want to test for any GUI Mac port under OS X, use
+\item If you want to test for any GUI Mac port under OS X, use
\texttt{\_\_WXOSX\_\_}.
\item If you want to test for any port under Mac OS X, including, for
example, wxGTK and also wxBase, use \texttt{\_\_DARWIN\_\_} (see below).
\twocolitem{\_\_UNIX\_LIKE\_\_}{Unix, BeOS or VMS}
\twocolitem{\_\_VMS\_\_}{VMS}
\twocolitem{\_\_WINDOWS\_\_}{any Windows}
+\twocolitem{\_\_WINE\_\_}{Wine}

\subsection{Hardware type}\label{hardwareconst}
-% Note: previous documentation referred to __SMARTPHONE__ as a generic (non-MS-specific) symbol
-% but we should go back to using it for a specific SDK, because trying to be

for them)}
+\twocolitem{WX\_PRECOMP}{is defined if precompiled headers (PCH) are in use. In
+this case, \texttt{wx/wxprec.h} includes \texttt{wx/wx.h} which, in turn,
+includes a number of wxWidgets headers thus making it unnecessary to include
+them explicitly. However if this is not defined, you do need to include them
+and so the usual idiom which allows to support both cases is to first include
+\texttt{wx/wxprec.h} and then, inside \texttt{#ifndef WX\_PRECOMP}, individual
+headers you need.}
\twocolitem{\_UNICODE and UNICODE}{both are defined if wxUSE\_UNICODE is set to $1$}

when compiling or using the library with the GUI features activated, if it is
exceptions has been switched off}
\twocolitem{wxNO\_THREADS}{if this macro is defined, the compilation options
don't include compiler flags needed for multithreaded code generation. This
-implies that wxUSE\_THREADS is $0$ and also that other (non wx-based) threading
+implies that wxUSE\_THREADS is $0$ and also that other (non-wx-based) threading
packages cannot be used neither.}
