Add a warning to drop database wait if there are still open handles on a table

  Add some more safety if MySQL tries to drop a table on which there are open handles

  Try to make sure DROP DATABASE does not cause a deadlock because we now let InnoDB wait MySQL does not have open handles to tables we drop

  DROP DATABASE required that the database name is in lower case to work; put it always to lower case in innobase_drop_database

Fix for ctypes on windows
Cleanup max_queries_per_hour

  Changed C++ style comments to ANSI C style.

into donna.mysql.fi:/home/heikki/mysqln

  If the default character set was set to non-latin1 then the collation order of DATA_CHAR and DATA_VARCHAR was not defined, and foreign key system tables did not work, because they contain DATA_VARCHAR columns

into mysql.sashanet.com:/reiser-data/mysql-4.0

got LOAD DATA INFILE replication from 3.23 master to 4.0 slave to work
for some reason query_cache now fails - will push anyway and document the
failure if I can repeat it.

  Still a little better error message for Harald Fuchs

  Add some error messages to help in tracking Harald Fuchs' foreign key failure
