Oops, I guess I must have confused you somehow (my fault) but I don't
see how my pointers are reversed ? Or maybe my code is unclear. If they
were reversed my program would not work anyhow, as it would try to
call a function (dumy_fnc) instead of displaying a submenu, and
vice-versa, calling a sub menu (menu_sub) when supposed to call the
dummy_fnc() function.

Yeah I noticed these were your changes... I did try to put the cast as
it was suggested to me (and by the GCC warning itseld), but
unsurprinsingly I got it wrong, thanks for the help on this !
