linux-ipsec: Compile errors for ipsec-0.7

I have run into the following error when I try to compile the utilities in IPSEC 0.7. I am running RH 5.0 with 2.0.33 kernel. The module compiles with the kernel cleanly, and it loads in without a problem.
/usr/include/linux is a symbolic link to /usr/src/linux/include/linux. It
looks like I have overlooked something simple. If anyone has run into this before, or if anyone has successfully complied this on a RH5.0 system, please respond. Thanks.
