That's your assumption. Which is not necessarily true. (Unless you're author
of cygpath, in which case you have full authority to tell me what it is
supposed to be.)
Man page and reference card both do not specify the exact argument format,
only the intended result format.
And just to be clear, windows in the core don't see a difference between the
path in format of "C:/whatever/..." or "C:\whatever\...".
This behavior is very, very old. Even older than Windows itself, if you know,
what "INT 21h" means.

Not true for the "outcome" part.

<stdout>:cygpath -w "/c/DAEMON1/anrdaemon/.profile"
C:\DAEMON1\anrdaemon\.profile

Which is far from original network path.

I already said that I'm sorry, that I forgot to mention what seems to be
critical bit of information.

To tell you, that was actually a good idea for me. I don't have an eternity to
type "/cygwhatever" every time I want to address another drive. So the idea
to map cygdrive to "/" was actually very handy, thanks to this mailing list
helping to finish and polish it.
