--- Comment #2 from Bruno Haible <bruno at clisp dot org> --- Indeed: * config/iconv.m4 (serial 26), compared to the current version (serial 32) in gnulib, lacks support for recent versions of macOS. * config/lib-ld.m4 (serial 2), compared to the current version (serial 13) in gnulib, lacks corrections for AIX and NetBSD. * config/lib-link.m4 (serial 4), compared to the current version (serial 35) in gnulib, lacks support for biarch platforms, for GNU/Hurd, for GNU/kFreeBSD, for mingw, and corrections for OpenBSD and Solaris 10. * config/lib-prefix.m4 (serial 2), compared to the current version (serial 23) in gnulib, lacks support for biarch platforms and corrections for NetBSD, Solaris OpenIndiana, and Solaris OmniOS. * config/host-cpu-c-abi.m4 is a new dependency and will need to be added (from gnulib) when the other files are upgraded.
