compilation error in mysys/my_getsystime.c fixed some redundant code removed sec_to_time, time_to_sec, from_unixtime, unix_timestamp, @@timestamp now use decimal, not double for numbers with a fractional part. purge_master_logs_before_date() fixed many bugs in corner cases fixed mysys/my_getsystime.c: compilation failure fixed sql/sql_parse.cc: don't cut corners. it backfires.
