Sorry, I don't understand how will this code reduce
the compile time?

It'd be nice but how can you do that?  The only way I
can see is using a default template parameter.

template<typename ImplTraits = DEFAULT_GUI_IMPL>
class window;

#define DEFAULT_GUI_IMPL XWinTraits

main()
{
  window win;   //X window

  //switching the default GUI platform

  #under DEFAULT_GUI_IMPL 
  #define DEFAULT_GUI_IMPL Win32Traits

  window win;  //Win32 window
}

I'd like to look at it.  Where is it? You mentioned
some yahoo thing. What is it?
