  94.     One or none of the following BUILDING_≈ conditionals is expected to be set during 
  95.     compilation (e.g. MrC -d BUILDING_FOR_SYSTEM7), the others should be left undefined.
  96.     If none is set, BUILDING_FOR_SYSTEM7_AND_SYSTEM8 is used.
  97.     
  98.         BUILDING_FOR_SYSTEM7                - Code is intended to run on System 7.x machine or earlier .
  99.         BUILDING_FOR_SYSTEM7_AND_SYSTEM8    - Code is intended to run on System 7 or Copland.
  100.         BUILDING_FOR_SYSTEM8                - Code is intended to run on Copland only.
  101.         BUILDING_PREEMPTIVE_CODE            - Code is intended to run as Copland server or driver.
  102.         
  103.     The following conditionals are set up based on which of the BUILDING_≈ flag (above) was specified.
  104.     They are used in throughout the interface files to conditionalize declarations.
  105.     
  106.         FOR_SYSTEM7_ONLY                    - In System 7. Not in Copland.
  107.         FOR_SYSTEM7_AND_SYSTEM8_DEPRECATED    - In System 7. Works in Copland, but there is a better way.
  108.         FOR_SYSTEM7_AND_SYSTEM8_COOPERATIVE    - In System 7. In Copland, but only for cooperative tasks.
  109.         FOR_SYSTEM7_AND_SYSTEM8_PREEMPTIVE    - In System 7. In Copland.
  110.         FOR_SYSTEM8_COOPERATIVE                - Not in System 7.  In Copland, but only for cooperative tasks.
  111.         FOR_SYSTEM8_PREEMPTIVE                - Not in System 7.  In Copland.
  112.         
  113.         FOR_OPAQUE_SYSTEM_DATA_STRUCTURES    - Always true for system 8, but can be set by developer to
  114.                                               true or false for System 7.  When true, the contents of 
  115.                                               many system data structures are removed from the interfaces.
  116.                                               In the future, the Mac OS will have fewer data structures 
  117.                                               shared between applications and the system.  The problem
  118.                                               with shared data is 1) the system has to poll the data
  119.                                               to detect changes made by an application, 2) it prevents
  120.                                               data structures from being changed in the future.
  121.                                               Procedural interface will be used instead.
  122.                                               
  123.         FOR_PTR_BASED_AE                    - This is a temporary fix for Copland DR1.  It is needed to
  124.                                               distinguish between pointer based and handle based AppleEvents.
  125.                                               If you are in the case of BUILDING_FOR_SYSTEM7_AND_SYSTEM8
  126.                                               and want to use new pointer base AppleEvents, you will need to
  127.                                               -d FOR_PTR_BASED_AE on your compiler command line.

  199.     OLDROUTINENAMES            - "Old" names for Macintosh system calls are allowed in source code.
  200.                               (e.g. DisposPtr instead of DisposePtr). The names of system routine
  201.                               are now more sensitive to change because CFM binds by name.  In the 
  202.                               past, system routine names were compiled out to just an A-Trap.  
  203.                               Macros have been added that each map an old name to its new name.  
  204.                               This allows old routine names to be used in existing source files,
  205.                               but the macros only work if OLDROUTINENAMES is true.  This support
  206.                               will be removed in the near future.  Thus, all source code should 
  207.                               be changed to use the new names! You can set OLDROUTINENAMES to false
  208.                               to see if your code has any old names left in it.
  209.     
  210.     OLDROUTINELOCATIONS     - "Old" location of Macintosh system calls are used.  For example, c2pstr 
  211.                               has been moved from Strings to TextUtils.  It is conditionalized in
  212.                               Strings with OLDROUTINELOCATIONS and in TextUtils with !OLDROUTINELOCATIONS.
  213.                               This allows developers to upgrade to newer interface files without suddenly
  214.                               all their code not compiling becuase of "incorrect" includes.  But, it
  215.                               allows the slow migration of system calls to more understandable file
  216.                               locations.  OLDROUTINELOCATIONS currently defaults to true, but eventually
  217.                               will default to false.
