Standard says... (in re: lseek):  EOVERFLOW: The resulting file
offset would be a value which cannot be represented correctly
in an object of type off_t.  The error message seems a reasonable
representation of that (off_t is required to be a signed integral
type).  Like Chuq says, this species (UNIX and relatives) is
unfortunately prone to not quite agreeing with each other in
boundary conditions, standards or no... and by the way, you can't 
count on the error /numbers/ being the same across systems, that's 
not part of UNIX standards.
