Since this change, I can't compile a kernel with TCP_SIGNATURE enabled:

...

depending the compat library objects
--- tcp_input.o ---

`tcp_signature_getsav':

/builds/current/src/sys/netinet/tcp_input.c:2715: error: too few arguments

Do I need to use some other option flag or other IPSEC options?  My config
is basically:

include "arch/i386/conf/GENERIC.MP"

options               IPSEC           # IP security
options               IPSEC_ESP       # IP security (encryption part; define
w/IPSEC)
options               IPSEC_DEBUG     # debug for IP security
options               TCP_SIGNATURE   # TCP MD5 Signatures, for BGP routing
sessions
