The task is to 
  (a) add a comment on indexes and 
  (b) increase the maximum length of column, table and the new index comments.

The patch committed on behalf of Yoshinori Matsunobu (Yoshinori.Matsunobu@Sun.COM).

Fix configure.js : set the variabes in cache, so they can overwrite cache variables in CMakeLists.txt

- mysql_install_db is in scripts dir now
- sql-bench is installed
-some extra support-files (e.g ini) are in support-files

 - Changes to the banner text
 - Use older AC_PROG_LIBTOOL (Bug#51009)

scripts/mysql_install_db.sh
 - Changes to banner text

Added --max-connections= argument to mysqltest and mtr
Small fix to first patch: forgot to check before free'ing connections array

in 'kostja@sun.com-20091210084103-l4f8u62u4evoy3dc'.

This file is necessary for Windows builds.

Some logic would group by suite always
Disable this if using --noreorder
Also fix getting array from collect_one_suite() in this case
Amended according to previous comment

There are 2 different share directories, one if builddir/share (with compiled errmsg.sys) 
and another one is $sourcedir/share and contains some /charsets/*.xml files.
second one should be refered to  as MYSQL_CHARSETSDIR and  MYSQL_SHAREDIR  $builddir/share

Compilation failure problems on non-i386 platforms.
Adding missing parenthesis.

If a prepared statement used both a MyISAMMRG table and a stored 
function or trigger, execution could fail with "No such table"
error or crash. 
The error would come from a failure of the MyISAMMRG engine
to meet the expectations of the prelocking algorithm, 
in particular maintain lex->query_tables_own_last pointer
in sync with lex->query_tables_last pointer/the contents
of lex->query_tables. When adding merge children, the merge
engine would extend the table list. Then, when adding 
prelocked tables, the prelocking algorithm would use a pointer
to the last merge child to assign to lex->query_tables_own_last.
Then, when merge children were removed at the end of
open_tables(), lex->query_tables_own_last
was not updated, and kept pointing
to a removed merge child.

The fix ensures that query_tables_own_last is always in
sync with lex->query_tables_last.

This is a regression introduced by WL#4144 and present only
in next-4284 tree and 6.0.

mysql-test/r/merge.result:
  Update results (Bug#47648).
mysql-test/t/merge.test:
  Add a test case for Bug#47648.
  Update the result file to reflect a fix of another bug
  in MyISAMMRG code: not maintaining lex->query_tables_own_last
  allowed a stored function or trigger to modify a merge table
  which was already updated by the main statement.
  It is not allowed for other storage engines, and should
  not be allowed for MyISAMMRG.
storage/myisammrg/ha_myisammrg.cc:
  When adding children to the list of tables to open,
  make sure that we properly set lex->query_tables_own_last.
  When removing the children, update lex->query_tables_own_last
  if necessary.
