--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed. Looks like GCC has incorrectly accepted this ever since the support
for using type aliases back in GCC 4.7.0.
GCC does reject defining a new type as the return type with typedef and when
declaring a function. So it looks like an oversight here even.
