AH transformation broken since 2.5.56

Hi,

Support for IPsec AH in net/ipv4/ah.c is broken since 2.5.56
(still broken in 2.5.59).
I tried with CONFIG_INET_AH=y and m, I got the same error :

make -f scripts/Makefile.build obj=net/ipv4
  gcc -Wp,-MD,net/ipv4/.ah.o.d -D__KERNEL__ -Iinclude -Wall -Wstrict-prototypes 
-Wno-trigraphs -O2 -fno-strict-aliasing -fno-common -pipe 
-mpreferred-stack-boundary=2 -march=i686 -Iinclude/asm-i386/mach-default 
-fomit-frame-pointer -nostdinc -iwithprefix include -DMODULE   
-DKBUILD_BASENAME=ah -DKBUILD_MODNAME=ah   -c -o net/ipv4/ah.o net/ipv4/ah.c
