This was not a regression. The Automake conditional was in fact not used, since the beginning of the getopt-posix and getopt-gnu modules. Apparently we considered this optimization "not worth it". But this optimization is OK. I verified that it works fine on - Linux/glibc, from CentOS 6 to Ubuntu 20.04 - Linux/musl - Hurd - FreeBSD, NetBSD, OpenBSD - macOS 10, 12 - AIX 7.1 - Solaris 9, 10, 11 - IRIX 6.5 Bruno
