    libstdc++: Define net::socket_base::message_flags operators as friends [PR
100285]

    The overloaded operators for socket_base::message_flags should only be
    defined when the message_flags type itself is defined. Rather than
    duplicate the preprocessor conditional, this moves the operators into
    the same scope as the type, defining them as hidden friends.

    As well as fixing the bug, this has all the usual advantages of hidden
    friends (they are not visible to normal name lookup for unrelated
    types).

    For consistency, do the same for the resolver_base::flags bitmask
    operators too.

    libstdc++-v3/ChangeLog:

            PR libstdc++/100285

    libstdc++: Add preprocessor checks to <experimental/internet> [PR100285]

    We can't define endpoints and resolvers without the relevant OS support.
    If IPPROTO_TCP and IPPROTO_UDP are both udnefined then we won't need
    basic_endpoint and basic_resovler anyway, so make them depend on those
    macros.

    libstdc++-v3/ChangeLog:

            PR libstdc++/100285
            * include/experimental/internet [IPPROTO_TCP || IPPROTO_UDP]
            (basic_endpoint, basic_resolver_entry, resolver_base)
            (basic_resolver_results, basic_resolver): Only define if the tcp
            or udp protocols will be defined.

I hope this one is fixed on trunk now.

--- Comment #17 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Fixed for 13.3

I doubt anybody is trying to use this code on arm-eabi with gcc-12 or gcc-11,
so not important to backport.
