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
