Wed Jul 13 03:30:36 1994  Jason Merrill  (jason@deneb.cygnus.com)

        * tree.h (TYPE_NEEDS_CONSTRUCTING): New macro.
        (tree_type): Add needs_constructing_flag.
        * function.c (assign_parms): If TYPE_NEEDS_CONSTRUCTING, pass by
        invisible reference.
        * calls.c (expand_call): Ditto.
