    Fix erroroneous use of '%zu' in elfcore_grok_win32pstatus
    
    As reported in [1], _bfd_error_handler() doesn't support '%zu'.
    
    module_name_size is always 32-bits in the data structure we are
    extracting it from, so use an unsigned int to store it instead.

            * elf.c (elfcore_grok_win32pstatus): Change name_size to unsigned
            int. Use '%u' format with  _bfd_error_handler to render it.
