    libstdc++: Fix -Wmismatched-tags warnings for _Safe_iterator [PR120112]

    This causes an ICE as shown in the PR, but it should be fixed in the
    library code anyway.

    libstdc++-v3/ChangeLog:

            PR c++/120112
            * include/bits/ptr_traits.h (_Safe_iterator_base): Use class
            keyword in class-head of declaration.
            * include/debug/debug.h (_Safe_iterator): Likewise.
