   Actually, POSIX does not define the standard C library.

Actually, it does.  See IEEE Std 1003.1-2004, XSH.  It doesn't define
the syntax for the C language though.

   Your challenge assumes that people think that Emacs is A Good
   Thing(tm).

Emacs is one of the core bits of the GNU system, you are free not to
use Emacs.
