I hesitate to report such things as "bugs", nevertheless, even if
every software which can be vanilla-installed from a cygwin mirror is
obligated to accept DOS paths (Is it?  That's OT here, of course).

Here and then I install stuff from elsewhere and I have been
accustomed to "`cygpath -u`" DOS paths if I find them.  I've learnt
now that I have been too careful for most cygwin stuff, but I think it
is sensible to be defensive as a general approach.

Just recently I have moved from NTEmacs to cygwin Emacs because I have
been unable to resolve the path misunderstandings (e.g. regarding
tempfiles) between NTEmacs and either Mailcrypt or bogofilter (the
latter two built on cygwin).  Hmm... maybe I should have asked
here...?

I should have reported my Emacs version:
GNU Emacs 21.2.1 (i686-pc-cygwin, X toolkit) of 2003-01-23 on DRACO,
running on Win2000.
  (expand-file-name "c:/test")   -> "/usr/haj/c:/test"
  (expand-file-name "c:\\test")  -> "/usr/haj/c:\\test"
(my cwd happens to be /usr/haj). Maybe CVS Emacs is different.
