It turns out that this test case no longer fails with the discrepancy
in numbers that was the original cause for disabling this test (and showed
potential genuine issues with the query cache). Therefore
this test is being enabled after some minor adjustment of error codes and
messages.
- Use mysql_system_tables.sql to create MySQL system tables in
all places where we create them(mysql_install_db, mysql-test-run-pl
and mysql_fix_privilege_tables.sql)
do not use '' as user in tests, because it picks the Unix login (which gives unexpected results if it is 'root')
(such behaviour is a feature of mysql_real_connect(), see the manual).
Note: The following tests fails
- fulltext (Sergei has promised to fix)
- rpl_charset (Guilhem should fix)
- rpl_timezone (Dimitray has promised to fix)
