More changes in MIT-pthreads to get them safer. Fixed also some link bugs at least in SunOS.
            Changed mysqld to work around a bug in
            MIT-pthreads. This makes multiple small
            SELECT operations 20 times faster. Now
            lock_test.pl should work.
          
            Added mysql_FetchHash(handle) to
            mysqlperl.
          
            The mysqlbug script is now distributed
            built to allow for reporting bugs that appear during the
            build with it.
          
            Changed libmysql.c to prefer
            getpwuid() instead of
            cuserid().
          
            Fixed bug in SELECT optimiser when using
            many tables with the same column used as key to different
            tables.
          
            Added new latin2 and Russian
            KOI8 character tables.
          
            Added support for a dummy GRANT command
            to satisfy Powerbuilder.
