+These are preprocessor symbols used in the wxWidgets source, grouped
+by category (and sorted by alphabetical order inside each category). All of
+these macros except for the \texttt{wxUSE\_XXX} variety is defined if the
+corresponding condition is true and undefined if it isn't, so they should be
+always tested using \texttt{#ifdef} and not \texttt{#if}.

-In fact, they should better all start with \_\_WX instead of \_\_ only. The
-only GUIs implemented for 2.0 are \_\_WXGTK\_\_, \_\_WXMSW\_\_ and
-\_\_WXMOTIF\_\_ yet. Any new ones, please start the define with \_\_WX.
+There are two wxWidgets ports to Mac OS. One of them, wxMac, exists in two versions: Classic and
+Carbon. The Classic version is the only one to work on Mac OS version 8. The
+Carbon version may be built either as CFM or Mach-O (binary format, like ELF)
+and the former may run under OS 9 while the latter only runs under OS X.
+Finally, there is a new Cocoa port which can only be used under OS X. To
+summarize:
+
+\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
+\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).
+\end{itemize}
+
+The convention is to use the \texttt{\_\_WX} prefix for these
+symbols, although this has not always been followed.

+\subsection{Feature tests}\label{featuretests}
+
+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
+predefines the symbols in the form \texttt{wxHAS\_FEATURE}. Unlike 
+\texttt{wxUSE\_FEATURE} symbols which are defined by the library user (directly
+in \texttt{setup.h} or by running configure script) and which must be always
+defined as either $0$ or $1$, the \texttt{wxHAS} symbols are only defined if
+the corresponding feature is available and not defined at all otherwise.
