* c-common.h (RETURN_NULLIFIED_P): Lose.
        * c-semantics.c (genrtl_return_stmt): Don't check it.

        Support named return value optimization for inlines, too.
        * decl.c (finish_function): Nullify returns here.
        * semantics.c (genrtl_start_function): Not here.
        (cp_expand_stmt): Don't mess with CLEANUP_STMTs.
        (nullify_returns_r): No longer static.  Just clear RETURN_EXPR.
        Also nullify the CLEANUP_STMT for the nrv.
        * cp-tree.h: Declare it.
        * optimize.c (declare_return_variable): Replace the nrv with the
        return variable.
        * typeck.c (check_return_expr): Be more flexible on alignment check.
        Ignore cv-quals when checking for a matching type.
