If you say so.  I've heard there are various LISP scripts
for non-Cygwin built emacsen to get them to parse the Cygwin
mount table so that they can handle the POSIX paths but I
don't use emacs so I don't know how they work and, of course,
I couldn't assume that you were using them.  Either way, if
it's not a Cygwin program, it's not going to understand the
POSIX paths natively so problems you have are really somewhat
off-topic for this list.
