--------------------
01g,26mar10,cww  LP64 adaptation
01f,12jun06,gls  added sigev_id and sigev_notifier_id to sigevent
01e,22feb06,pes  Get pthread_attr_t def from base/b_pthread_attr_t.h
                 instead of pthreadCommon.h.
01d,26jan06,mil  Moved union sigval into base type file.
01c,07dec05,gls  added additional sigevent members for SIGEV_THREAD support
01b,07dec05,gls  added SIGEV_THREAD
