+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

+\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.
+
+Currently the following symbols exist:
