    This file contains a pthread.h headerconversion,

    used by systhrd, preferably in a somewhat compatible notation
    (compared to the other OSes).

    As a start, I simply used libc_r

  Revision 1.6  2004-12-22 21:29:24  marco
   * rtlevent kraam. Checked (compile): Linux, FreeBSD, Darwin, Windows
  	Check work: ask Neli.

  Revision 1.5  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 1.4  2004/05/28 18:23:55  marco
   * fixes for darwin specific external name '' behaviour. Must still be
  tested

  Revision 1.3  2004/05/26 20:05:21  marco
   * 2nd attempt

  Revision 1.2  2004/05/26 19:23:17  marco
   * first iteration

  Revision 1.1  2004/01/04 20:05:38  jonas
    * first working version of the Darwin/Mac OS X (for PowerPC) RTL
      Several non-essential units are still missing, but make cycle works

  Revision 1.2  2003/11/27 20:24:10  michael
  + Redefined ppthread_mutex_t

  Revision 1.1  2003/11/18 22:33:42  marco
   * moved from systhrds.pp
