values.c valops.c ChangeLog

        * values.c (value_fn_field): when physical name not found, do not
        error, but return null.
        * valops.c (value_struct_elt): when name and args match does not
        mean it is the one, some times a typedef class can have the same
        memeber method and args. This probably will not happen with new
        version of g++, but it does happen in old g++ and cause gdb error.
