Is there an easy way to update a mysqldump file from version 9.11 to 10.11?
Well,

I figured out that if you use the backticks ("`") around the table name (like mysqldump uses in the comment-separator sections, e.g. `call`), it works as expected. 

So, the above should look like:

--
-- Table structure for table `call`
--

DROP TABLE IF EXISTS `call`;
CREATE TABLE `call` (
  path varchar(255) NOT NULL default '',
  call_num int(12) unsigned NOT NULL auto_increment,
  date datetime NOT NULL default '0000-00-00 00:00:00',
  idf varchar(4) NOT NULL default '404',
  location varchar(255) default NULL,
  who_req varchar(8) default NULL,
  who_res varchar(8) default NULL,
  PRIMARY KEY  (path,call_num)
) ENGINE=MyISAM;

--
-- Dumping data for table `call`
--


Hope that helps.
