Although I'm one of the authors of that particular library I now prefer to
use this other library instead:

https://github.com/fdopen/uwt
https://opam.ocaml.org/packages/uwt/

where "Uwt.Pipe" is a Unix domain socket on Unix and a named pipe on
Windows. I'm very happy with "uwt" -- it seems to be very stable and
reliable, despite the relatively low version number.

Personally I don't want my final executables to depend on the cygwin.dll
but I don't mind if my development environment uses cygwin for the Unix
utilities like "make", "vi" etc. I usually install OCaml one Windows using
this installer:

http://fdopen.github.io/opam-repository-mingw/installation/

-- this installs everything you need (including Cygwin). I then `opam
install` my dependencies and `make`, like I can on Unix. My resulting .exe
files are independent of cygwin.dll and I ship them as-is.

Hope this helps a little,

Dave
