Don't you mean rather:

AL_FUNC(int, _main, (void *_mangled_main, int argc, char *argv[]));

#if (!defined ALLEGRO_NO_MAGIC_MAIN) && (!defined ALLEGRO_SRC)

   extern int _mangled_main(int argc, char *argv[]);

   #define main                                               \
                                                              \
      main(int argc, char *argv[])                            \
      {                                                       \
         return _main((void *)_mangled_main, argc, argv);     \
      }                                                       \
                                                              \
      int _mangled_main

#endif    ?


I tried that too, but it of course imposes that the user main() be defined
with the right prototype. However, the big advantage is that END_OF_MAIN()
goes away.

I totally agree (albeit 'int AL_MAIN(int arg, char *argv[])' is more
correct).
