Looks a bit like the system headers are not in either of the directories
you've specified, or any default path. Have you tried adding the
-print-search-dirs option, to show where it's looking? You can then
compare with a place you do have system headers. ;)

If that doesn't do it, I'd run the new compiler with only -v, to check
its frame of mind.
