This is a somewhat different problem since in this case Emacs is a
cygwin program.
  cygpath -m  /home/kbrown/html/index.html
will return a suitable windows name
(c:/cygwin17/kbrown/html/index.html  on my system)

It should be relatively simple to incorporate that transformation
directly into a cygwin-specific function. I did something similar for
cygwin make some years ago to get it to build windows emacs.
I'll see if I can find the code. It's been a while.
