First "*and*" - it's emphasised. Are you are using recent kde ?
Gtk-webkit doesn't do emphasis (looking at epiphany-2.28), gecko does
(italics in forefox-3.6.3plugin), lynx does (different colour). So, I'm
reluctant to add '*' for emphasis in the text.
I'm also reluctant to give a false impression that setting ABI is need on
*any* architecture, it's only an i?86 thing. Yes, I know that we only
support x86, but I still feel that unqualified statements can spread
confusion. I'm willing to concede the point on this, if that is the
consensus.
Insetting the ABI=32 ./configure looks a lot nicer. I've put a revised
version there for this - boxing ('userinput') seems to work, and insets
the line, but the box is an extra line deep on my browsers. /me misses
Manuel's advice.
For the second note ( and still assuming I've understood the problem
correctly! ), this isn't strictly cross-compiling. The reference in the
ticket shows there were no i486- tools. It's "detuning" the i?86 build.
On glibc the book uses "-march=i486 -mtune=native" to build for i486.
We've had people building on one i?86 machine and trying to run the
binaries on lesser machines for as long as I've been using LFS.
I'm happy to drop the second note if everyone wants to enforce
"build on the machine you will run on" throughout the book.
Thanks for these comments,
