-// On Windows when compiling a dll, wx prevents the compilation
-// of the class wxStreamToTextRedirector (why ? it is a nightmare...)
-// The blocking symbol is wxHAS_TEXT_WINDOW_STREAM.
-// Note also that wxStreamToTextRedirector use the fact that wx is 
-// compiled with the option WX_USE_STD_STREAMS in which case 
-// wxTextCtrl inherits from std::streambuf and the redirection 
-// can be done simply by setting the std::cout buffer to the 
-// one of the wxTextCtrl. 
-// So on windows, we have to redirect manually std::cout to mwxTextHistory.  
-// Finally, on all systems we made our redirection class to redirect both to
-// the WxConsole and to printf in order to get a console trace when 
-// the appli crashes (we could also imagine to log in a file...)
-// This is why we finally wrote our own redirection which is crossplatform
-// (drawback : not optimal on Unix platform; we could think of 
-// a particular implementation...).
