[patch] add GNU/kFreeBSD support into boehm-gc also for amd64/x86-64 cpu

[Petr Salinger]

Hi,

would be possible to merge GNU/kFreeBSD support in boehm-gc
into gcc also for amd64/x86-64 cpu.

Those changes to boehm-gc have been just accepted by upstream, see thread started by 
http://www.hpl.hp.com/hosted/linux/mail-archives/gc/2007-January/001535.html

Please, could you add this tiny patch into both trunk and gcc-4.2 branch.

         * include/private/gcconfig.h: handle amd64/x86-64 cpu under GNU/kFreeBSD
         * os_dep.c: Likewise.


Thanks in advance,

          Petr
