    * splitted default_extended from support_extended

  Revision 1.4  1998/08/11 00:05:24  peter
    * $ifdef ver0_99_5 updates

  Revision 1.3  1998/08/08 12:28:11  florian
    * a lot small fixes to the extended data type work

  Revision 1.2  1998/05/12 10:42:45  peter
    * moved getopts to inc/, all supported OS's need argc,argv exported
    + strpas, strlen are now exported in the systemunit
    * removed logs
    * removed $ifdef ver_above
