The Item_func_if::fix_length_and_dec() function when calculating length of
result doesn't take into account unsigned_flag. But it is taken when
calculating length of temporary field. This result in creating field that
shorter than needed. Due to this, in the reported query 40.0 converted to 9.99.
The function Item_func_if::fix_length_and_dec() now adds 1 to the max_length if
the unsigned_flag isn't set.

internal charset to one associated with currently being handled query.
To note such a query can come from interactive client either.
There was a discussion within replication team and Monty who's suggestion won.
It avoids straightforward parsing of all `set' queries that could affect client side
character set.
According to the idea, mysql client does not parse `set' queries but rather cares of
`charset new_cs_name' command.
This command is generated by mysqlbinlog in form of exclaiming comment (Lars' suggestion)
so that enlightened clients like `mysql' knows what to do with it.
Interactive human can switch between many multi-byte charsets during the session
providing the command explicitly.
To note that setting new internal mysql's charset does not
trigger sending any `SET' sql statement to the server.
client/mysql.cc:
BUG#16217 revealed the problem of switching between charsets in mysql client.
Such switching is necessary in a case when being scanned query consists of
multi-byte chars and internal charset was initialized differently. mysql finds
`/' escape and misiterprete it
while in fact one could be a part of a multi-byte symbol like the bug page reported.
This patch extends mysql `charset' command, '\C' shortcut.

and possibly server crash in mysqld v5.0.
Reported MyISAM table was created in mysqld 4.1 and contains varchar field.
When binary files of that table was moved to 5.0, mysqld treats that varchar
field as a string field.
In order to make grouping server calculates group buffer, and because
that field is string server assumes it has fixed length and doesn't add
space for length, but later that field is converted to varchar field.
Due to this, when field values were actually copied, additional space for
length bytes is taken and buffer overrun occurs, which may lead to server crash.
The calc_group_buffer() function now reserves additional space for length
bytes for VAR_STRING fields, like for VARCHAR fields.
sql/sql_select.cc:
Fixed bug#16752 Binary table files created in mysqld v4.1 caused buffer overrun and possibly server crash in mysqld v5.0.
The calc_group_buffer() function now reserves additional space for length
bytes for VAR_STRING fields, like for VARCHAR fields.
fix for bug#8461
BUG 8461 - TRUNCATE returns incorrect result if 2nd argument is negative
Reason: Both TRUNCATE/ROUND converts INTEGERS to DOUBLE and back to INTEGERS
Changed the integer routine to work on integers only.
This bug affects 4.1, 5.0 and 5.1
Fixing in 4.1 will need to change the routine to handle different types individually.
5.0 did had different routines for different types already just the INTEGER routine was bad.
