Here's what happens on my machine:

  /cygdrive/c/DAEMON1anrdaemon.profile

  C:/DAEMON1anrdaemon.profile

  C:/DAEMON1anrdaemon.profile

  /cygdrive/c/DAEMON1/anrdaemon/.profile

  C:/DAEMON1/anrdaemon/.profile

Alternatively:

  $ cygpath -u '\\DAEMON1\anrdaemon\.profile'
  //DAEMON1/anrdaemon/.profile

  $ cygpath -m '\\DAEMON1\anrdaemon\.profile'
  //DAEMON1/anrdaemon/.profile

  $ cygpath -lm '\\DAEMON1\anrdaemon\.profile'
  //DAEMON1/anrdaemon/.profile

There's something weird in your bash settings.  Usually bash will fold the
backslashes before using the string as argument to the child process.  See
the behaviour with echo:

  $ echo \a
  a
  $ echo \\a
  \a
  $ echo "\a"
  \a
  $ echo "\\a"
  \a
  $ echo '\a'
  \a
  $ echo '\\a'
  \\a

So what cygpath gets as argument in your first example is usually

  \DAEMON1anrdaemon.profile

I don't know what the difference in your settings is, though.  Something
with readline, maybe.
