They are specifically exempted from getting picked up by autorebase for this very reason. If you rebased them manually or somehow managed to overwrite them with other versions (opam sometimes does this and it seems you are trying some sort of OCaml build whenjh this happens, which may have done this), you should re-installl all OCaml packages of your installation. > ---------------- > Fatal error: cannot load shared library dllunix > Reason: flexdll error: cannot relocate RELOC_REL32, target is too far: > 0xfffffffc02088b5f 0x2088b5f > ---------------- > > I searched solutions for this new problem.

Again, it seems you are trying to do a build with OCaml, you must ensure it doesn't create libraries you already have installed from Cygwin packages and certainly to not overwrite them.
