Yep, I forgot about binutils bug#620448.  If you put this script
somewhere before /usr/bin on your $PATH, make it executable, and name
it "as", that should work around it.

	#!/bin/sh
	exec /usr/bin/as --size-check=warning "$@"

If you're using gcc 4.6, the change from de2a8cf9 (e.g., grab it
using "git cherry-pick de2a8cf9") is also needed.
