Thank you.  I found two bugs.

  * offset shoule be applied for network byteorder, even on little
    endien machines.

  * integer size should be checked even for unsigned integers.

I think I fixed this.  Try the latest CVS, or soon releasing 1.6.2.
Thank you again.

p.s.
I also appreciate the staffs in the Unversity of Tokyo, who supplied me
an account to Alpha Linux machine.
