Heres the patch for reordered headers.  Building as we speak.  Hard to fully
verify since Ada doesn't seem to bootstrap on trunk at the moment:

+===========================GNAT BUG DETECTED==============================+

Bulid log (native build on gcc76.fsffrance.org) can be found at
http://toolchain.lug-owl.de/buildbot/deliver_artifact.php?mode=view&id=4292383
for build
http://toolchain.lug-owl.de/buildbot/show_build_details.php?id=472655 .

So it's probably one of these two commits:

	r228586 = 54ac7405ce75c141dae33532d491d5793fb583e3
		Jan Hubicka  <hubicka@ucw.cz>
		Do not use TYPE_CANONICAL in useless_type_conversion

It's one of Jan's patches. I've got them reverted locally and Adabuilds fine.
