+Same as \texttt{const\_cast<T>(x)} if the compiler supports const cast or 
+\texttt{(T)x} for old compilers. Unlike \helpref{wxConstCast}{wxconstcast},
+the cast it to the type \arg{T} and not to \texttt{T *} and also the order of

+\texttt{(T)x} for old compilers. Unlike \helpref{wxStaticCast}{wxstaticcast},
+there are no checks being done and the meaning of the macro arguments is exactly
