values we use #defined here:
/* "Special" directory offsets. */
#define END_OF_DIRECTORY_OFFSET ((long)-1)
#define START_OF_DIRECTORY_OFFSET ((long)0)
#define DOT_DOT_DIRECTORY_OFFSET ((long)0x80000000)
So long as telldir() doesn't return any of these,
we should work fine. We don't expect the cookies
to be consecutive or in any order for that matter.
So I would take issue with your statement:

signed offset in Samba which is not handled correctly. The cookies are not
necessarily consecutive as you move through a directory.
