My reasoning here is that, from a distribution perspective, man-pages’s main
branch describes the future. CentOS 7 carries glibc 2.17, but it also carries
an old version of man-pages, which (hopefully) accurately describes the
environment there. Many example programs in man pages don’t build on older
distributions ;-).

Stephen
