Fix for storing negative values in decimal fields
Fix for FLUSH TABLE with HANDLER

Add missing file to VC++ project

into mysql.com:/home/mysql_src/mysql-4.1

has (in mysql-test-run) a slave-net-timeout=10. So the 'sleep 1' below
was converted in 'sleep 10', so slave thought that connection was down,
so reconnected, so got an additional (fake) Rotate event, which shifted
the positions displayed by SHOW SLAVE STATUS.
