I dunno whether anyone here know about Emacs, but I thought I would
ask.

In a previous setup (Windows XP, 32-bit), I believe that running the
Emacs function
     (file-exists-p "c:/")
produced t.

Now, with the latest Cygwin, Windows 7, 64-bit, emacs-version
"23.3.1",
     (file-exists-p "c:/")
     nil
     (file-exists-p "c:\\")
     nil
I notice it because it broke some code, my .emacs startup file to be
precise.  It was a quick and easy way to check whether it was running
under Windows.

I have a workaround,
     (file-exists-p "/mnt/c")
but that only "works" because I "know" that I have changed the drive
prefix from /cygdrive to /mnt.

Can it be made to work again?  Any suggestions on how to tell in Emacs
whether I'm running under Windows?
