  On the other hand, if you wish to be portable, ignore _DLL_InitTerm,
  _dllmain, and __dll_initialize completely, and use C++.

  Declare a class that represents the concept of your DLL

      struct MyLibrary {
          MyLibrary () ;
          ~MyLibrary () ;
      } ;

  Declare a single, static-duration, DLL-wide, instance of your derived
  class in one of your DLL source files :

      struct MyLibrary TheDLL ;

  Note that `TheDLL' can have internal or external linkage (it matters
  not).  The important thing is that there is *one* static-duration
  instance of that class in your whole DLL.

  Perform all of your initialisation and cleanup in the constructor and
  destructor of your DLL class :


      MyLibrary::MyLibrary ()
      {
          WinRegisterClass(/*...*/) ;
      }

      MyLibrary::~MyLibrary () { /* Nothing for now */ }

  These will then be called for `TheDLL' when the DLL is loaded and when
  it is unloaded.

  This has three advantages over the _DLL_InitTerm &c. method :

      1.  It's portable across all compilers.  There's no need for
          complex #if...#elif...#elif...#elif...#endif clauses.

      2.  It works for both statically and dynamically linked libraries.

      3.  You are guaranteed that the C++ runtime is available within
          the constructor and destructor of `TheDLL' (calling constructors
          and destructors of static-duration objects is *done* by the
          C++ runtime, after all).

  This method is thus highly recommended over the _DLL_InitTerm &c. method.
