Hello,
 
  I'd like to use the cygwin build of ocaml through emacs.  I'm using vanilla emacs and cygwin, with the shell connection cygwin-mount.el.  For some reason, when I use the binary windows edition of ocaml, I can send ocaml interrupts through emacs with C-c C-c.  With the cygwin built version, though, I can't get any interrupts to work.  I tried sifting through the 21 different signals but couldn't find out what ocaml is doing with C-c C-c.  The emacs window just flashes.  I can't use this version if I can't interrupt, but I need the regular expressions of the cygwin version.  Has anyone else had this problem? 
 
Best,
 
Sean
