In 4.1 there are 3 calls; 2 of them will be fixed when there is a merge;
here I fix the 3rd, new one.

by MAX/MIN in some cases:
SELECT coercibility(max(s1)) from t1;

Subselect collation and derivation was not processed
correctly:

create table a select (select s1 from t1);
select * from t1 where s1 = (select s2 from t1);

  Revise 4.1 Windows-install instructions.

(fixed BUG#943)

CREATE TABLE t1 (s1 CHAR(5) COLLATE latin1_german1_ci,
                 s2 CHAR(5) COLLATE latin1_swedish_ci);
SELECT * FROM t1 WHERE s1 = s2;

count HAVING clause elements with select list elements, because agregate function can be present in it (BUG#922)

bugs #701 and #783 - old .frm files were read in incorrectly in 4.1 (each field was assigned a charset, BLOBs were converted to TEXT)

have in fact no effect, because in 4.0 the slave always runs with --skip-innodb.
In 4.1, mysqld accepts option --innodb which can override --skip-innodb.
So I add this option to the test.
When the updated test (using InnoDB tables) from 4.0 will be merged
into 4.1, with this good .opt file, we'll have a meaningful test in 4.1.
Until then, the test in 4.1 will pass but be useless.
And in 4.0, it will stay useless forever.
("it" = the part of the test which tests replication of foreign_key_checks)
