Yes, ocamlc's output requires ocamlrun to execute since it's only
bytecode and is portable (modulo C bindings).
You need to use ocamlopt instead of ocamlc, it will generate native
executables which are not portable.
That ocamlopt's output requires cygwin1.dll means you've run the cygwin
OCaml compiler; it depends on what you've installed and there are
binaries of non-cygwin ocaml compilers available on http://caml.inria.fr
(there might also be a cygwin package with one but it's probably a bit
old)
