I have "GNU Emacs 23.1.50.1 (i386-mingw-nt5.1.2600) of 2009-10-14 on
LENNART-69DE564 (patched)" (known as EmacsW32, latest version that Lennart put
online).

Library is file "c:/Program Files/Emacs/emacs/lisp/calc/calc.elc", and I see
(on line 1544 of the =.el= file):

#+begin_src emacs-lisp
(defvar calc-command-flags)
#+end_src

ELC seems well compiled from that EL, as times report:

--8<---------------cut here---------------start------------->8---
  -rw-rw-rw-  1 Fabrice Aucun 138805 2009-10-14 02:45 calc.el
  -rw-rw-rw-  1 Fabrice Aucun 103841 2009-10-14 02:46 calc.elc
--8<---------------cut here---------------end--------------->8---

Setting it myself to nil -- I have no idea why I must do this! -- :

#+begin_src emacs-lisp
(setq calc-command-flags nil)
#+end_src

has the effect that many examples now work.

Not all, though. For example,

#+begin_src calc
2*e
#+end_src

returns =nil=:

#+results:
: nil

Best regards,
  Seb
