        * dwarf2read.c (read_namespace): Pull out name-generating code
        into namespace_name. Rename previous_namespace to previous_prefix
        and processing_current_namespace to processing_current_prefix..
        (namespace_name): New function.
        (add_partial_symbol): Substitute uses of pdi->name with
        actual_name.
        * cp-support.h: Rename processing_current_namespace to
        processing_current_prefix.
        Update copyright year.
