That makes sense to me, but I have other issues.
Before the jh branch is merged, there needs to be some textual changes
to describe what we are trying to do. The issues of advantages/
disadvantages of 64-bit vs 32-bit systems needs to be discussed.
Perhaps the best place may be in section "1.2 What's new since the last
release" or perhaps earlier.
The section "iv. Host System Requirements" probably needs to be expanded
too.
I'd like to see the question answered. "I have a 64-bit system. How
can I build a 32-bit system?"
There also needs to be more explanation in the text interspersed with
the instructions. For instance in "5.4. GCC-4.2.1 - Pass 1" we have:
"Also, the --with-arch flag is only necessary for x86 machines."
The WITHARCH variable seems to be a configure option, but I can't find
it in ./configure --help or with a grep of configure. In any case, I
have Pentium 4 CPU. Why do I want to use --with-arch=i486 instead of
--with-arch=pentium4.
The M64 variable on the other hand is a gcc compiler option. Why are we
using -m64 for 64 bit architectures? The info page says that is a
deprecated option.
