--- Comment #14 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jonathan Wakely <r...@gcc.gnu.org>: https://gcc.gnu.org/g:793ed718b522b15e2d758eca953feeec1979fe2c commit r14-1650-g793ed718b522b15e2d758eca953feeec1979fe2c Author: Jonathan Wakely <jwak...@redhat.com> Date: Fri Jun 9 12:15:21 2023 +0100 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.
