http://lists.freebsd.org/pipermail/freebsd-current/2011-December/030484.html
>How-To-Repeat:
Just csup latest code using that exact release, cd /usr/src and make buildworld
>Fix:
This was also described into mailing lists in a follow-up email : 
http://lists.freebsd.org/pipermail/freebsd-current/2011-December/030500.html

As Clang (at least in this release) seems to use GCC-Like sintax for _Noreturn 
... one could check compiler (and version, if necessary) and add this 
workaround definition:

#define _Noreturn __attribute__ ((noreturn))
