  12  * Revision 42.8  2003/01/18 19:10:11  chodorowski
  13  * Instead of using the _AROS or __AROS preprocessor symbols, use __AROS__.
  14  *
  15  * Revision 42.7  2000/08/10 17:53:19  stegerg
  16  * removed a debug output.
  17  *
  18  * Revision 42.6  2000/08/08 20:36:51  stegerg
  19  * UtilityBase on AROS is not of type struct Library *, but
  20  * struct UtilityBase *. BTW: Why????????? I think we should
  21  * fix this. Also locale.library seems to have this "problem".
  22  *
  23  * Revision 42.5  2000/08/08 19:29:54  chodorowski
  24  * Minor changes.
  25  *
  26  * Revision 42.4  2000/08/08 13:51:34  chodorowski
  27  * Removed all REGFUNC, REGPARAM and REG macros. Now includes
  28  * contrib/bgui/compilerspecific.h where they are defined.
  29  *
  30  * Revision 42.3  2000/08/07 21:49:06  stegerg
  31  * fixed/activated REGFUNC/REGPARAM macros.
  32  *
  33  * Revision 42.2  2000/07/04 05:02:22  bergers

  41  *
  42  * Revision 41.11  2000/05/09 20:33:28  mlemos
