	Right.  That's a cmd.exe-ism  -- As Christofpher F. says,
it's not been true in Cygwin in a long time (I don't remember it being
true, ever, but I never tried using it to see if it was supported).

	If you are in a 'bash' shell -- bash doesn't maintain
an internal, drive-specific "CWD", for each DOS drive -- it just
has 1 CWD(CurrentWorkingDir) as there is no concept of 'drivers'.  
C:\\, works due to path mangling -- likely when bash sees it, it's
already "[/YourCygPrefixHere]/c/ or root depending on your mount points.

	If "C:" worked it could be confusing, Unless, "C" was your
*only* drive -- then people might forget and think that C: meant
your CWD on your "current drive"...but really, there's no current 
drive, and I'm not sure cygwin should inherently support such a vague
syntax.  What would it mean in a POSIX context?  Would it mean
"/c/$PWD"  or "/c/", or (for /c/ == '/' i.e. c is your root partition),
would it mean '/' or $PWD?
