  (g_b_init_get_sid_identifier_authority, GetSidIdentifierAuthority_Proc)
  (get_sid_identifier_authority): Remove, not used.
  (globals_of_w32): Don't set g_b_init_get_sid_identifier_authority.
  (init_winsock): Remove useless assignment.
  (open_process_token, get_token_information, lookup_account_sid)
  (get_sid_sub_authority, get_sid_sub_authority_count, get_file_security)
  (get_security_descriptor_owner, get_security_descriptor_group)
  (is_valid_sid, equal_sid, get_length_sid, copy_sid)
  (get_native_system_info, get_system_times, init_user_info, crlf_to_lf)
  (is_unc_volume, GetCachedVolumeInformation, get_volume_info)
  (is_fat_volume, open_unc_volume, read_unc_volume, close_unc_volume)
  (unc_volume_file_attributes, convert_from_time_t)
  (create_toolhelp32_snapshot, process32_first, process32_next)
  (open_thread_token, impersonate_self, revert_to_self)
  (get_process_memory_info, get_process_working_set_size)
