24
* Previously, the mysql_priv.h file contained a number of conditional
25
* #ifdef DRIZZLE_SERVER blocks which made it very difficult to determine
26
* which headers and definitions were actually necessary for plugins to
27
* include. The file, and NOT mysql_priv.h, should now be the main included
28
