Hmmm, I don't follow here. I seem to recall that I wrote
--with-header specifically to support the case of $build != $host ==
$target. So I'm surprised that you say that --with-headers is not the
right approach. You're suppose to use --with-headers for the header
files for $target. It's not wrong to use it when $host == $target.
But I'm probably misunderstanding something.
