-Standard C++ streams can cause problems on several platforms: they work quite
-well in most cases, but in the multi-threaded case, for example, they have many
-problems. Some Borland compilers refuse to work at all with them.
-@todo is this still true?
+wxWidgets provides its own set of stream classes in order to be
+independent of the standard C++ stream class and their different
+implementations.
 
 Besides, using @c std::iostream on Linux makes impossible to write programs that are
 binary compatible across different Linux distributions.

 wxStreamBase is the base definition of a stream. It defines, for example, the
 API of OnSysRead(), OnSysWrite(), OnSysSeek() and OnSysTell(). These functions are
