FreeBSD *redacted* 6.0-RELEASE FreeBSD 6.0-RELEASE #0: Wed Nov 2 19:07:38 UTC 2005 root@rat.samsco.home:/usr/obj/usr/src/sys/GENERIC amd64
>Description:
A powerpc build (any release) fails on amd64. The same tree on a 32-bit host works fine. I believe it will fail on other 64-bit arches though I haven't verified this.
>How-To-Repeat:
make TARGET_ARCH=powerpc buildworld
>Fix:
I applied the following diff supplied by Ruslan Ermilov: worked fine.
