I still have to make a test case for :

UPDATE from sub-select with derived table

into sinisa.nasamreza.org:/mnt/work/mysql-4.1

a bit more ucs2 compatibility 

into sinisa.nasamreza.org:/mnt/work/mysql-4.1

CREATE TABLE tname (a CHAR(10) COLLATE latin1_de)

CREATE TABLE tname (a CHAR(10) ASCII)
  as a synonym for
CREATE TABLE tname (a CHAR(10) CHARACTER SET latin1)

   "fieldname CHAR(n) UNICODE"
as a synonym to
   "fieldname CHAR(n) CHARACTER SET ucs2"

into eagle.mysql.r18.ru:/home/vva/work/MANY_INIT_COMMANDS/4.1

select .. UNION select some_column;

This is exhibited in sub-selects and derived tables.

into bar.mysql.r18.ru:/usr/home/bar/mysql-4.1.wrk

into eagle.mysql.r18.ru:/home/vva/work/MANY_INIT_COMMANDS/4.1

into eagle.mysql.r18.ru:/home/vva/work/MANY_INIT_COMMANDS/4.1

into eagle.mysql.r18.ru:/home/vva/work/sanya_bug/4.1

fixed method definition (overloading instead of redefinition)
fixed time expression type definition

Changed timestamp to return string in YYYY-MM-DD HH:MM:SS format.
DATE_ADD() and related functions now returns correct DATE/DATETIME type depending on argument types.
Now all tests passes, still some work left to remove warnings in log files from mysql-test-run
