mariadb/include/myisam.h
unknown e689fbc458 Fixed compiler warnings by adding casts and changing variable types 
Fixed bug that caused change_user.test to fail
Fixed bug that caused mysql_client_test to fail


include/myisam.h:
  Fixed prototypes
mysql-test/r/create.result:
  Fix that test works even if Maria is not used for temporary tables
mysql-test/t/create.test:
  Fix that test works even if Maria is not used for temporary tables
sql/mysqld.cc:
  Fixed that default value of max_join_size is set correctly; It needs to match usage in set_var.cc
sql/set_var.cc:
  Fixed test, now when max_join_size is initialized correctly
sql/sql_select.cc:
  Fixed that one can compile without -DUSE_MARIA_FOR_TMP_TABLES
storage/maria/ma_blockrec.c:
  Fixed compiler warnings by adding casts
storage/maria/ma_checkpoint.c:
  Fixed compiler warnings by adding casts
storage/maria/ma_create.c:
  Fixed compiler warnings by adding casts
storage/maria/ma_delete_table.c:
  Fixed compiler warnings by adding casts
storage/maria/ma_loghandler.c:
  Fixed compiler warnings by adding casts and changing types for variables
  Changed translog_new_page_header to use changing integer instead of calling time() as time() is a slow call and will give same results when calling many times withing one second
storage/maria/ma_pagecrc.c:
  Fixed compiler warnings by adding casts
storage/maria/ma_recovery.c:
  Fixed indentation
storage/myisam/ha_myisam.cc:
  Fixed wrong types for variables
  Changed chk_data_link() and repair*() functions to take my_bool as argument
storage/myisam/mi_check.c:
  Fixes to handle that param.test_flag is now ulonglong
storage/myisam/myisamchk.c:
  Fixes to handle that param.test_flag is now ulonglong
support-files/compiler_warnings.supp:
  Fixed line numbers
