via https://github.com/mirage/mirage-fs-unix/pull/3 (thanks @dsheets):

PATH_MAX may not be defined and the resolved_path==NULL feature should be used to get a malloc'd buffer (and then copy to an OCaml string and free).
GNU realpath may set errno to EACCES or ENOENT and then return a non-NULL pointer to the failing prefix
