			Change bool in C code to my_bool Added to mysqltest --enable_parsning and --disable_parsing to avoid to have to comment parts of tests Added comparison of LEX_STRING's and use this to compare file types for view and trigger files.

|       tz_tables - list of implicitly used time zone tables received
 | |
|                   from my_tz_get_table_list() function.
 | |
| 
 | |
|   NOTE
 | |
|     This function relies on my_tz_get_table_list() implementation.
 | |
| 
 | |
|   RETURN VALUE
 | |
|     TRUE  - if table points to the beggining of tz_tables list
 | |
|     FALSE - otherwise.
