On native Windows (i.e. not Cygwin), flexdll_dlopen is a stub function for converting an ANSI filename to Unicode and then calling
flexdll_wdlopen. However, it's permitted to pass NULL in order to get a handle to the running process, but this isn't implemented in the stub, which fails.
As far as I can tell, this means ocamlnat has been broken since OCaml 4.06!
