-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
+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)

-Note to implementors: although some of the symbols above don't start with
-\texttt{\_\_WX} prefix, they really should always use it, so please do start
-any new symbols with it.

+The convention is to use the \texttt{\_\_WX} prefix for these
+symbols, although this has not always been followed.

+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

building wxBase code, either as a standalone library or as part of the

+exceptions has been switched off}

+packages cannot be used neither.}
