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
  ./configure
  make world.opt
  make install

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

I am not using Cygwin, but would it be related with this:

https://github.com/alainfrisch/flexdll

(Alain Frisch seems to be one of the persons maintaining flexdll...)

[isabelle-dev] Problem with ocaml nums.cma on Cygwin64

2017-10-06 Thread Makarius 
We are moving towards uniform x86_64 support in Windows, including
x86_64-cygwin (which is likely to behave better concerning infamous "DLL
rebase" problems).

Presently (e.g. in Isabelle/0b3fa8e22f22) this causes a new problem with
OCaml, see also my thread on the Cygwin mailing list:
https://cygwin.com/ml/cygwin/2017-10/msg00037.html

  $ ocaml nums.cma
  Cannot load required shared library dllnums.
  Reason: /usr/lib/ocaml/stublibs/dllnums.so: flexdll error: cannot
  relocate RELOC_REL32, target is too far: 0xfffc02c4c753  0x2c4c753.


I am unsure what the situation of OCaml on Cygwin64 really is.

Maybe some OCaml expert can say more about it.
