ipf40a26 - ip_nat.c compile error - Tru64 5.1A

[jeff . stelzner]

I get the following error from a 'make tru64' under Tru64 5.1A when trying
to build ipf40a26:

cc -std1 -msg_disable expandeddefined -g -I..      -DTRU64=1885

        hlen = tcp->th_off << 2;

Stop.

The ipf40a25 kit seemed to build and run OK.
Is this a known issue, and are any patches available to encourage this
build to be more successful?

Thanks - Jeff
