I installed https://github.com/fdopen/opam-repository-mingw, merlin and tuareg successfully in Cygwin. Now I have installed Windows emacs and changed .emacs to enable modes to edit Ocaml files.
Is this how the setup is supposed to be ? Can Windows emacs work with Cygwin OCaml tools like this ?
If not then I request for details to setup emacs in Cygwin.
Update : Now my init.el is this
;; Added by Package.el. This must come before configurations of
;; installed packages. Don't delete this line. If you don't want it,
;; just comment it out by adding a semicolon to the start of the line.
;; You may delete these explanatory comments.

cygwin-mount.el is in the site-lisp folder.
I don't see any change when I open a .ml file or when I type M-x merlin-mode
Are you sure Tuareg is actually loaded? If you go to *scratch*, type (locate-library "tuareg") and execute it (type C-xC-e when the cursor is after the closing brace), what do you see in the echo area?
In the directory where you installed Tuareg, there should be a file tuareg-site-file.el. If so, put in your ~/.emacs, the line:
(load "/path/to/tuareg-site-file")
to enable Tuareg.
