FWIW, I know nothing about zsh; I don't use it; but your statement above
triggered an association, so here's a WAG.  Many applications assume that
having multiple trailing slashes is equivalent to having one slash (and it
is in Linux).  I have seen applications blindly appending a "/" to a path,
just to make sure it ends in a / (don't know if zsh does it).  This, of
course, doesn't work in Cygwin when the path is just a "/", because a "//"
prefix is special.  I'd look through the path composition pieces of the
zsh code to see if "/" is ever appended -- I think that might be your
culprit.  The fix would be to check whether a path ends in "/" before
appending one.  HTH,
