RHEL/CentOS 6 is still a common development target, and I strongly feel that we should continue to support it out of the box. RHEL 5 is starting to fade, though, so we may finally be able to bump to something newer than autoconf 2.59 and automake 1.9.6.
When the original distributor no longer supports an operating system, we can drop support too. We've used this heuristic with Solaris, IRIX, etc. to good effect. For RHEL, release 5 is scheduled for end-of-life on 2017-03-31 so we can drop support for it then. RHEL 6's EOL is currently scheduled for 2020-11-30, and RHEL 7's is 2024-06-10. See:
