  $Log$
  Revision 1.12  2004-11-19 13:15:14  marco
   * external rework. Mostly done.

  Revision 1.11  2004/11/14 12:21:08  marco
   * moved some calls from unix to baseunix. Darwin untested.

  Revision 1.10  2004/05/31 18:03:51  jonas
    * moved fpgeterrno/fpseterrno declarations to before their actual usage

  Revision 1.9  2004/03/04 22:15:16  marco
   * UnixType changes. Please report problems to me.

  Revision 1.8  2004/01/04 21:04:08  jonas
    * declare C-library routines as external in libc for Darwin (so we
      generate proper import entries)

  Revision 1.7  2004/01/03 23:56:11  marco
   * fix for 1.0 compability issue

  Revision 1.6  2003/12/30 12:26:21  marco
   * FPC_USE_LIBC

  Revision 1.5  2003/12/10 17:13:43  marco
   * property support under ifndef ver1_0

  Revision 1.4  2003/12/10 17:08:33  marco
   * property errno defined

  Revision 1.3  2003/09/14 20:15:01  marco
   * Unix reform stage two. Remove all calls from Unix that exist in Baseunix.

  Revision 1.2  2003/06/03 14:23:45  marco
   * Moved prototypes outside of baseunix. And shared with linux for now

  Revision 1.1  2003/01/05 19:01:28  marco
   * FreeBSD compiles now with baseunix mods.

  Revision 1.1  2002/12/18 16:44:09  marco
   * more new RTL

  Revision 1.2  2002/11/14 12:17:28  marco
