There were two CVS commits.  From 1.11 -> 1.12, the change was from an 
int cast to
(intptr_t) around line 120.  I doubt that broke it.

 From 1.10-> 1.11, I see that I changed two things.  I added "L" onto 
the 65535's
in ADDCARRY.  I doubt that broke anything.  But later in the file, I 
changed some ints
to uint32_t's.  Can you try changing those back to int32_t?

 cvs diff -r 1.10 -r 1.11 -u in_cksum.c

to see the change.  It almost has to be adding the unsigned.

Let me know what works and post the diff.  There wasn't much changed.
