+modification history
+--------------------
+01e,17jan11,pad  Added lockedPthread and joinedPthread fields in pthreadCB
+		 (defect 242878). Renamed a couple of other fields for clarity.
+		 For robustness, made the VALID status flag a magic number.
+01d,11nov10,pad  Moved internal types from pthread.h in here.
+01c,02nov10,pad  Removed _pthreadSetCancelType() declaration as it is now an
+		 inline routine, renamed pthread_setcanceltype_inline(), in
+		 pthreadLib.c (part of defect 233318).
+01b,14may10,jpb  Added pthreadLibInit prototype.
