Update.
2003-07-07 Ulrich Drepper <drepper@redhat.com>
* descr.h (struct pthread): Add pid field.
* allocatestack.c (allocate_stack): Initialize pid field in descriptor.
(__reclaim_stacks): Likewise.
* init.c (sigcancel_handler): If __ASSUME_CORRECT_SI_PID is defined
also check for PID of the signal source.
(__pthread_initialize_minimal_internal): Also initialize pid field
of initial thread's descriptor.
* pthread_cancel.c: Use tgkill instead of tkill if possible.
* sysdeps/unix/sysv/linux/fork.c: Likewise.
* sysdeps/unix/sysv/linux/pt-raise.c: Likewise.
* sysdeps/unix/sysv/linux/pthread_kill.c: Likewise.
* sysdeps/unix/sysv/linux/raise.c: Likewise.
