[zebra 23045] Compilation error

Hi,

I try to install Zebra to my system files (netkit). First ./configure went
without errors but when I type make an error occur, see below.

|| echo './'`ipforward_sysctl.c
ipforward_sysctl.c:38: error: 'IPCTL_FORWARDING' undeclared here (not in a
function)
ipforward_sysctl.c: In function 'ipforward':
ipforward_sysctl.c:48: warning: pointer targets in passing argument 4 of
'sysctl' differ in signedness
make[2]: *** [ipforward_sysctl.o] Error 1
make[2]: Leaving directory `/zebra'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/'
make: *** [all] Error 2

About my OS I use Debian Linux :
hassan:~# uname -a
Linux hassan 2.6.18-4-686 #1 SMP Wed May 9 23:03:12 UTC 2007 i686 GNU/Linux


Please Help me

Best regards,
