{
History:
Added overlay functions for Pchar->Strings, functions
and procedures.
14 Jul 2000.
Changed tWBArg.wa_Lock from a pointer to a longint.
15 Aug 2000.
Fixed tDiskObject.
Member tDiskObject.do_CurrentX was defined as a pointer,
should be longint.
17 Aug 2000.
Added functions and procedures with array of const.
For use with fpc 1.0.7. Thay are in systemvartags.
05 Nov 2002.
Removed amigaoverlays, use smartlink instead.
05 Nov 2002.
Added the defines use_amiga_smartlink and
use_auto_openlib. Implemented autoopening of
the library.
14 Jan 2003.
Update for AmigaOS 3.9.
A lot of new const and new records.
New functions
FUNCTION AddAppWindowDropZoneA
FUNCTION ChangeWorkbenchSelectionA
FUNCTION CloseWorkbenchObjectA
FUNCTION MakeWorkbenchObjectVisibleA
FUNCTION OpenWorkbenchObjectA
FUNCTION RemoveAppWindowDropZone
FUNCTION WorkbenchControlA
Varargs functions are in systemvartags.
02 Feb 2003.
Changed integer > smallint,
cardinal > longword.
09 Feb 2003.
