that is not strictly speaking Zsh fault. Zsh is using globbing when
completing file names and globbing does not return Cygwin mount points. Just

cd /
echo *

or simply

echo /*

The bug is in the way Cygwin treats own mount points. Zsh has workaround for

     This style is used when completing files and looked up without a
     tag.  Its values are of the form `DIR:NAMES...'.  This will add
     the NAMES (strings separated by spaces) as possible matches when
     completing in the directory DIR, even if no such files really

     This can be useful on systems that support special filesystems
     whose top-level pathnames can not be listed or generated with glob
     patterns.  It can also be used for directories for which one does
     not have read permission.

So set it to

zstyle ':completeion:*:fake-files' /:'c d cygroot' /cygroot:'c d ...' ...

(IIRC virtual root is called /cygroot).

If you come up with a script that parses mount table and automatically
creates this style we can add it to distribution so whoever packages Zsh for
Cygwin could use it in /etc/zshrc by default. I once intended to do it but I
do not use Cygwin now.
