Alas make buildworld fails for the past few days:
===> usr.sbin/config
<snip>
In file included from config.c:1:
/usr/include/stdlib.h:102: conflicting types for `restrict'
/usr/include/stdlib.h:102: previous declaration of `restrict'
/usr/include/stdlib.h:102: warning: redundant redeclaration of `restrict' in same scope
/usr/include/stdlib.h:102: warning: previous declaration of `restrict'
/usr/include/stdlib.h:103: conflicting types for `restrict'
<snip>
(and also stdio.h, string.h, sys/types.h, select.h)

Someone posted a link to the failure that I get, so I'll crib:

I tried that as well, but the new binary also dumps core, but works
well with previous versions of the firewall.  Even back as far as
my kernel.working from May 7 2003.
