This one is the second from the series.  Few months ago I checked
compiler passes bootstrap and make check after each patch.  I didn't
run make check for each patch after the latest rebase due to decision
to not commit separate patches but to commit whole series instead.  So
I just checked it compiles at every patch boundary.
