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?

TIA,
