Subject: [Caml-list] Bug? Printf, %X and negative numbers

$ ocaml
        Objective Caml version 3.06

# Printf.printf "%08X\n" (1 lsl 30);;
C0000000
- : unit = () 
# Printf.printf "%010X\n" (1 lsl 30);;
00C0000000
- : unit = ()
# 

I expected output of 40000000, not C0000000.  Note that this isn't a case 
of simple sign extension, as the second example demonstrates.  Where'd the 
extra bit come from?
