I have some problems with compiling new kernel:

Sorry, forgot to check in a fix.  Apply this patch:

  http://www.freebsd.org/~kris/ufs_lookup.c.diff

(you'll need to specify the path by hand)

Now this compiles, but :

Stop in /usr/src/sys/modules/mac_lomac.

where -Werror is defined - in the Makefile? :)
Is it safe to just remove it for security/ and continue with build?

BTW I removed "options ADAPTIVE_GIANT" as it is unknown with your sources.

Yes, it is gone with 8.0. Disable the module builds because some of them like this one probably need compile fixes. If you need a subset of modules use MODULES_OVERRIDE=list (in /etc/make.conf)
