 I'm actually trying to build x2goclient, which pulls in
 libssh-0.10.4_0+kerberos5+universal.

 libssh build fails with:

 {{{
 :info:build
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_devel_libssh/libssh/work/libssh-0.10.4/examples/sshnetcat.c:241:18:

 }}}

 I'm not sure if I can remove `-Werror` with macports.

 I'm attaching the full bld log.

Comment:

 > I'm not sure if I can remove `-Werror` with macports.

 Ports should not use `-Werror`. However, Xcode 12 and later consider
 [wiki:WimplicitFunctionDeclaration implicit declaration of functions] to
 be an error even without `-Werror`, and it looks like Xcode 14.3 may have
 become even more picky about this kind of thing. The code will need to be
 fixed.

 Probably we should try updating the port to 0.10.5 first. The problem may
 already have been fixed there.
