I did discover this info:

Running M-x version <RET> prints a `G' in *Messages" buffer

Running M-x eval-expression <RET>
Eval: (emacs-version) <RET>

Does print version info in *Messages*
  "GNU Emacs 21.2.1 (i686-pc-linux-gnu, X toolkit, Xaw3d scroll bars)
   of 2002-08-28 on astest"

Further, something I should have tried first:
Calling emacs -q -no-site-file, then M-x version, and the version info
does appear in *Messages*.  So apparently some local setting causing this.

If you mean in /usr/share/emacs/21.2/lisp/version.el, then yes it does
around line 74.
