  Revision 1.2  2003-01-08 22:32:28  marco
   * Small fixes and quick merge with 1.0.x. At least the compiler builds now,
      but it could crash hard, since there are lots of unimplemented funcs.

  Revision 1.1.2.7  2001/07/21 19:17:11  carl
  + added MAX_ARGS define

  Revision 1.1.2.6  2001/07/08 04:45:28  carl
  + updated type definitions

  Revision 1.1.2.5  2001/07/07 15:41:42  carl
  + added missing definitions

  Revision 1.1.2.4  2001/07/07 04:38:54  carl
  + added missing S_X constants

  Revision 1.1.2.3  2001/07/06 12:07:05  carl
  * correct definitions

  Revision 1.1.2.2  2001/07/06 11:59:35  carl
  + added missing constants
  (still missing mode_t bit definitions)

  Revision 1.1.2.1  2001/07/06 02:59:56  carl
  + first revision for BeOS
