	gdbtypes.h stabsread.c cp-valprint.c ChangeLog

        * gdbtypes.h : add a field 'ignore_field_bits in cplus_specific,
        and macros to handle the bits.
        * stabsread.c (read_one_struct_field): add VISIBILITY_IGNORE, and
        for field of length 0, set this bit on.
        * cp-valprint.c (cp_print_value_fields): for VISIBILITY_IGNORE
        field, print <no value>.
