Update.
2002-12-18 Ulrich Drepper <drepper@redhat.com>
* descr.h (struct pthread) [NEED_DL_SYSINFO]: Add sysinfo member.
* sysdeps/i386/tls.h (tcbhead_t): Add sysinfo member.
Define SYSINFO_OFFSEET if NEED_DL_SYSINFO is defined.
(INIT_SYSINFO): New #define.
(TLS_TP_INIT): Use INIT_SYSINFO.
* sysdeps/unix/sysv/linux/libc_pthread_init.c (__libc_pthread_init):
At test to make sure SYSINFO_OFFSET value is correct.
* sysdeps/unix/sysv/linux/i386/dl-sysdep.h: New file.
