    bfd     * cofflink.c (_bfd_coff_generic_relocate_section): Provide a value
            for undefined symbols which will not generate extra warning
            messages about truncated relocs.
    
    ld      * testsuite/lib/ld-lib.exp (ld_link_defsyms): For PE based targets
            define the __main and ___main symbols in terms of the main symbol.
