    libstdc++: Tweak common_iterator::operator-> return type [PR104443]
    This adjusts the return type to match the resolution of LWG 3672. There
    is no functional difference, because decltype(auto) always deduced a
    value anyway, but this makes it simpler and consistent with the working
            PR libstdc++/104443
            * include/bits/stl_iterator.h (common_iterator::operator->):
            Change return type to just auto.
    (cherry picked from commit b5f5d1b36edbcd7d923f2e2653e54e52637c715b)
