Saved Searches not working with MySQL 4.0

I just tested an upgrade from 1.5 to 1.6.8022 and have found that any search involving a smart group is giving a database error.

"Database Error Code: Unknown table 'civicrm_group_contact' in where clause, 1109"

I found that the issue was due to the query generated by CRM/Contact/BAO/Query.php in the 'else' clause of the "if ( $config->mysqlVersion >= 4.1 )" test on line 1689 (this is also about the only place that mysql 4.0 is special cased in the project).

I changed the WHERE parameters to use the table alias $gcTable = "`civicrm_group_contact-" .implode( ',', array_keys($value) ) ."`"; instead of "civicrm_group_contact" to get rid of the error and everything now seems ok.

This is pretty easy to reproduce, just change the config to specify mysql 4.0 and do a search involving a smart group to exercise this code path.
