Age as Defined by Emacs Release Notes

Emacs is (considering) dropping support for some operating systems that I have actually used! I'm officially getting old.

An excerpt from NEWS.23.1:

** The following platforms will be removed in a future Emacs version:
If you are still using Emacs on one of these platforms, please email
emacs-devel@gnu.org to inform the Emacs developers.

*** Old GNU/Linux systems based on libc version 5.

*** Old FreeBSD, NetBSD, and OpenBSD systems based on the COFF
  executable format.

*** Solaris versions 2.6 and below.

Plus some others that I haven't used.
