+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

+Mac situation is a bit confusing so a few extra words to explain it: there are
+2 wx ports to Mac OS. One of them, wxMac, exists in 2 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}
