To what value? (Spoiler: 1024 is wrong. All other values are also wrong.)
PATH_MAX does not exist on the Hurd because it has no limits.
You should do things like check for get_current_dir_name(3) in libc
and use it if it is present, and dynamically allocate all pathname
storage instead of hardcoding the maximum length.
