Thanks.

Fixed up for as_a_nullable -> safe_as_a, and committed to trunk as
r214196, having bootstrapped&regrtested on x86_64-unknown-linux-gnu
(Fedora 20) albeit in combination with patches 30-39, and verified that
it builds standalone both for that target, and for pdp11-aout, the
latter to give coverage for HAVE_cc0.

Am attaching what I committed.
