amd64 cross-world completed on FreeBSD
BSD Forums writes "FreeBSD's Dag-Erling Smorgrav reports the successful cross-world build of the amd64 tree (A tinderbox is system designed to test builds and report failure. In the FreeBSD case, tinderboxes build world [the base system], GENERIC, and if applicable LINT kernels. Dag-Erling Smorgrav currently runs all the tinderboxes by cross-building from i386)."
It's important to note that this anouncement only affects FreeBSD -current. -current also supports alpha, ia64 (Itanium2), pc98 and sparc64.
The -stable branch currently only supports i386, pc98 and alpha. When the 5.x branch will be deemed to be stable, all of -current's architectures will get official ISO images and testing using a wider audience will be possible. At this point work on 6-current will begin.

FreeBSD has been working on alpha, sparc64, ia64, powerpc, mips, s390, arm, and amd64 ports for a while and they've grabbed a little NetBSD code along the way to improve driver portability (adding in their own contributions as well) while NetBSD has grabbed FreeBSD's kqueue code and other goodies. Read the release notes for the various architectures to get a progress report. 5.x branch is the one that supports much more architectures and what not.
