That's an error in the compiler -- CIL may require the most recent version
ocaml. I built it with 3.09 on win32/cygwin. However, the version that
comes with Cygwin's package management is currently 3.08.1. Try grabbing
3.09 from the website, building it, and installing it over the cygwin
default.

If that doesn't work for you, I have put up a precompiled x86-cygwin copy
of CIL (as used in this project). If you drop it in over the cil directory
in cs655-hw-5 you should be able to compile nf.ml with cygwin's ocaml 3.08.
Verbose example for clarity:

  yuki:~/Desktop/655/cs655-hw-5$ make nf
  ocamlc -I cil/obj/x86_WIN32 -I cil/obj/x86_LINUX -c nf.ml
  ocamlc -I cil/obj/x86_WIN32 -I cil/obj/x86_LINUX -o nf str.cma unix.cma cil.cma nf.cmo
  yuki:~/Desktop/655/cs655-hw-5$ ./nf.exe

  0 errors reported.

In unrelated news, there's also a v2 of the codepack that fixes two or
three small typos in nf.ml.

Great!

I'm glad to hear that you got to the chewey fun center at the center of the
HW5 tootsie pop!
