Commit dd377bfb authored by monty@mashka.mysql.fi's avatar monty@mashka.mysql.fi

Fixed problem when comparing a key for a multi-byte-character set. (bug 152)

Use 0x.... as strings if 'new' mode. (bug 152)
Don't report -max on windows when InnoDB is enabled. (bug 332)
Reset current_linfo;  This could cause a hang when doing PURGE LOGS.
Fix for row numbers in EXPLAIN (bug 322)
 Fix that USE_FRM works for all table types (bug 97)
