--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Most likely due to this part of the patch from c-typeck.c:
+             else if (TREE_CODE (op0) =3D=3D INTEGER_CST
+                      && maybe_warn_shift_overflow (location, op0, op1)
+                      && flag_isoc99)
+               int_const =3D false;=
