Given that "errno" is a global variable, this is actually a good thing.

How many times have you wished for:

     errno = lseek(int fildes, off_t newoffset, int whence, off_t *oldoffset)

Or:

     errno = lseek(int fildes, off_t *offset, int whence)

Instead of:

     off_t
     lseek(int fildes, off_t offset, int whence)

So that you didn't have to worry about the sign bit?
