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.
