/* CONDITIONAL COMPILE ############################################################# */
/* 
 defines cut down on checks/code space/memory usage - the memory usage can add up quick for large amounts
 of items that are to be filtered creating many instances of the _HIDDEN_DATA structure.
 Also cuts down on the checks if they are not needed inside PostDirectoryControl() which is a heavily
 called function.
 This allows versions to be compile that only filter on cretain class types, obsessive way to save memory.
 **** * ATLEAST ONE * **** of these ** MUST ** be defined 1, if not then why are we even bothering
