- Revision 1.3 2006/11/20 21:20:59 savage
- Updated to work in MacOS X
-
- Revision 1.2 2006/04/18 18:38:33 savage
- fixed boolean test - thanks grudzio
-
- Revision 1.1 2004/03/30 21:53:55 savage
- Moved to it's own folder.
-
- Revision 1.5 2004/02/15 22:48:35 savage
- More FPC and FreeBSD support changes.
-
- Revision 1.4 2004/02/14 22:36:29 savage
- Fixed inconsistencies of using LoadLibrary and LoadModule.
- Now all units make use of LoadModule rather than LoadLibrary and other dynamic proc procedures.
-
- Revision 1.3 2004/02/14 00:23:39 savage
- As UNIX is defined in jedi-sdl.inc this will be used to check linux compatability as well. Units have been changed to reflect this change.
-
- Revision 1.2 2004/02/14 00:09:19 savage
- Changed uses to now make use of moduleloader.pas rather than dllfuncs.pas
-
- Revision 1.1 2004/02/05 00:08:19 savage
- Module 1.0 release
-
- Revision 1.1 2003/05/11 13:18:03 savage
- Newest OpenGL Headers For Delphi, Kylix and FPC
-
- Revision 1.1 2002/10/13 13:57:31 sg
- * Finally, the new units are available: Match the C headers more closely;
