--- Comment #8 from Segher Boessenkool <segher at gcc dot gnu.org> --- To expand a bit: st_other with value 1 was reserved before, and now it isn't anymore. Any tool that silently ignores the "special case" of reserved values will not work correctly (it might sometimes do what is wanted though). This is true everywhere always.
