I don't have any POSIX docs and ANSI-C (1989) says nothing about lseek().
K&R 2nd edition page 175 top even says:

long lseek(int fd, long offset, int origin);

and DEC Unix unistd.h and sys/types.h say

extern off_t lseek __((int , off_t , int ));
typedef long off_t; /* file offset */

also the libc-linux man page and include files mention

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

so I'd say I've to complain to Linus ?

this is true for 32 bit platforms like Intel but IMHO it's not true
for 64 bit architectures (here: DEC ALpha AXP)
