Thank you Bruce, Aleksandar. Sorry for the late reply, I thought I would get
individual messages back to my inbox. Now I know they come back bundled up in
Digests (can I change this in any way?)

OK, but is that not what we do in the LFS 6.4 or 6.5 as well? I am not trying
to argue, just to better understand. In both LFS and CLFS we build such that we
gradually detach ourselves completly from the host, right? Then what does the
64 bit compilation have to do with the detachment process once the target and
the host acrhitectures are the same?
Aleksandar's reply kind of underlines this:

Put this way, it makes sense to me. What I would like to obtain is a 64 bit
machine that has 32 bit libraries as well, so that I do not limit the system to
64 bit applications. 64 bits I need for those of my own. And, for this purpose,
what Aleksandar wrote, that is,

seems logical to me.
While on this note, I do ot quite understand why one would not re-compile GRUB
as well:

Thank you, Bruce, I'll look at it.
Thank you All, again,
