jdk15 port compile error on FreeBSD 6.2

[Peter Oxenham]

I am trying to upgrade to the latest 1.5 JDK via the ports system and am getting the following error.

This is a similar error as posted on other posts and the fix there was to add the following to /etc/make.conf

    CFLAGS+=-fno-tree-vrp

    see http://unix.derkeiler.com/Mailing-Lists/FreeBSD/current/2007-10/msg00475.html

The problem is that this seems to be a gcc 4+ specific parameter and I'm getting an error when I try this on my 6.2 box.

Any suggestions on how I can get jdk15 compiled correctly?

Thanks
Peter
