        * parse.c (check_component, parse_union): Whitespace.
        (set_syms_host_assoc): For a derived type, check if the module
        in which it was declared is one of the submodule ancestors. If
        it is, make the components public. Otherwise, reset attribute
        'host_assoc' and set 'use-assoc' so that encapsulation is
        preserved.
