      /* Hello!
       * This thing looks trivial, right? Guess again :-)
       * Observe:
       * 1) Because of the way plugins are done within the scummvm core
       *    (read: slightly dirty) it is required that the plugins
       *    (built as dlls in win32 systems) have to "backlink" into the
       *    main executable. More specifically, the dlls have to call
       *    functions from the (separately built) main module.
       *    This means trouble for wince, as the dynamic linker does not
       *    resolve imported symbols to a dll from an executable.
       * 2) But wait! DLLs can have any way of importing/exporting symbols
       *    between them. Hmmm...
       *
       * Right! The solution is thus: We build everything as a dll. This means
       * the individual engines (plugins) and also the scummvm core application.
       * It is in fact "The sub-DLL solution" described over at edll
       * (ref. http://edll.sourceforge.net/).
       *
       * The last thing to watch out for is that in a plugin build, we already
       * supply a WinMain function (this one, right here) which supersedes
       * SDL's one. So we need to do the startup things SDL does in scummvm
       * before running SDL_main.
       *
       * All this leaves us, for this source file, to do this crummy little... */
