  $Log$
  Revision 1.6  2004-09-09 20:29:06  jonas
    * fixed definition of pthread_mutex_t for non-linux targets (and for
      linux as well, actually).
    * base libpthread definitions are now in ptypes.inc, included in unixtype
      They sometimes have an extra underscore in front of their name, in
      case they were also exported by the packages/base/pthreads unit, so
      they can keep their original name there
    * cthreadds unit now imports systuils, because it uses exceptions (it
      already did so before as well)
    * fixed many linux definitions of libpthread functions in pthrlinux.inc
      (integer -> cint etc)
    + added culonglong type to ctype.inc

  Revision 1.5  2004/08/25 21:42:11  jonas
    * fixed pthread type definitions for darwin and made them generic

  Revision 1.4  2004/01/22 13:46:14  marco
  bsd

  Revision 1.5  2004/01/04 20:08:45  jonas
    * moved SIG_MAXSIG and wordsinsigset constants from bunxtype.inc to
      ptypes.inc (already there for Darwin)

  Revision 1.4  2004/01/04 01:11:28  marco
   * a new qod port of the freebsd rtl. To be refined in the coming days.

  Revision 1.3  2003/01/17 22:13:47  marco
   * some updates

  Revision 1.5  2003/01/03 13:11:32  marco
   * split into ptypes and ctypes
