It's working for me (tested once again). Weird!?

I don't have problems in "NT" Emacs (the Windows binaries), only with
Cygwin Emacs -- which is the target I'm supposed to follow.

If I don't set them in the above way, when running `M-x R', I'm blocked
with the message:

--8<---------------cut here---------------start------------->8---
Warning (emacs): None of 'w32-short-file-name, 'win32-short-file-name,
or 'mswindows-short-file-name are defined!
You will have to manually set   ess-program-files (in ess-custom.el) to
the correct "8.3"-style directory name.
--8<---------------cut here---------------end--------------->8---

Best regards,
