  - POSIX compliance patches (aka, removing the coreutils hack).
  - Upgraded to a glibc that supports POSIX message queues.
  - Pass --enable-const to ncurses.
+ - Readline in Ch.6, and add uses of it. For example, Bash accepts the
+   --with-external-readline (or something like that) argument, and E2fsprogs
+   can be more "interactive" when compiled w/ a patch against it.
