I'm not sure I understand exactly what you're saying: is it because of
limitations of cygwin-mount or is it because something else makes it
impossible for cygwin-mount to do the right thing?

I can't imagine why the same problem wouldn't show up if you try to run
`emacs' from cygwin's bash.
And please understand that I don't mean to say that your suggestion is
wrong, just that the same should be done in startup.el to match your
change in server.el.

IIRC /home is "mounted" from /c/cygwin/home, and cywin-mount has/had
support for such rewriting, tho it may not be enabled by default, or may
not have been updated to work with recent Emacsen/Cygwin.
