After studying the hints provided here and on the Cygwin mailing list, I
have now rebuilt OCaml from the official sources provided by Cygwin:

  cd /usr/src/ocaml-4.04.2-1.src/ocaml-4.04.2
  make world.opt
  make install

The resulting /usr/local/bin/ocaml appears to work for now, and is
probably outside the auto rebase mechanism.
