    This file contains a pthread.h headerconversion,
    and should contain an interface to the threading library to be
    used by systhrd, preferably in a somewhat compatible notation
    (compared to the other OSes).

    As a start, I simply used libc_r

  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
