When I use -gstabs+ the type looks like this:

    (gdb) p *type
    $1 = {
      code = TYPE_CODE_CHAR, 
      name = 0x83e6574 "char", 
      tag_name = 0x0, 
      length = 2, 
      upper_bound_type = 0, 
      lower_bound_type = 0, 
      objfile = 0x0, 
      target_type = 0x0, 
      pointer_type = 0x0, 
      reference_type = 0x0, 
      cv_type = 0x83d4980, 
      as_type = 0x83d4980, 
      flags = 1, 
      nfields = 0, 
      fields = 0x0, 
      vptr_basetype = 0x0, 
      vptr_fieldno = -1, 
      type_specific = {
	arg_types = 0x0, 
	cplus_stuff = 0x0, 
	floatformat = 0x0
      }
    }

HTH,
