Is there anything special one has to do when doing a make world

kernel and make world as everywhere else?
The same as everywhere else.

So, I take it that this means that all the userspace programs, ports,
packages, utilities, etc. do *not* take advantage of the 64-bit
extensions. That is, only the kernel gets the benefit of the
wider word. Is that correct?
No, everything is 100% native.

OK, these may be really stupid questions but:
1) How does make world know whether to build 32-bit or 64-bit binaries?
It always uses the native format. amd64 == 64 bit, i386 == 32 bit
Don't mean to beat this to death, but can you say just a bit more
about this please. If I am running an i386 kernel on 64-bit capable
processor, I assume I will get 32-bit binaries or not? IOW, what
triggers makeworld to do something in 32- vs. 64-bit mode? The
*kernel* currently executing or the underlying hardware capability?
I'm pretty sure this is all documented ;) The "i386" version of FreeBSD
is 32-bit. You can run it on any i386-compatible machine, including
amd64/em64t machines. The "amd64" version of FreeBSD is 64-bit.
