Update.
2002-07-19  Ulrich Drepper  <drepper@redhat.com>

	* configure.in: Add test for __thread support in compiler.
	* config.h.in: Add HAVE___THREAD.
	* Makefile (headers): Remove errno.h, sys/errno.h, and bits/errno.h.
	* include/sys/errno.h: Moved to...
	* stdlib/sys/errno.h: ...here.  New file.
	* stdlib/errno.h: New file.  Moved from...
	* include/errno.h: ...here.  Changed into an internal header defining
	libc-local things like __set_errno.
	* stdlib/Makefile (headers): Add errno.h, sys/errno.h, and
	bits/errno.h.
	* elf/dl-minimal.c: Include <tls.h>.  Define errno as thread-local
	variable if USE_TLS && HAVE___THREAD.  Don't define __errno_location
	either.
	* elf/rtld.c (_dl_start): Add code to initialize TLS for ld.so
	from...
	(_dl_start_final): ...here.  Add code to initialize tls elements from
	bootstrap_map.
	* sysdeps/generic/errno-loc.c: Define errno as thread-local variable
	if USE_TLS && HAVE___THREAD.
	* sysdeps/generic/bits/errno.h: Remove __set_errno definition.
	* sysdeps/mach/hurd/bits/errno.h: Likewise.
	* sysdeps/standalone/arm/bits/errno.h: Likewise.
	* sysdeps/standalone/bits/errno.h: Likewise.
	* sysdeps/unix/bsd/bsd4.4/bits/errno.h: Likewise.
	* sysdeps/unix/sysv/aix/bits/errno.h: Likewise.
	* sysdeps/unix/sysv/hpux/bits/errno.h: Likewise.
	* sysdeps/unix/sysv/linux/bits/errno.h: Likewise.
	* sysdeps/unix/sysv/linux/hppa/bits/errno.h: Likewise.
	* sysdeps/unix/sysv/linux/mips/bits/errno.h: Likewise.
	* sysdeps/unix/sysv/sysv4/solaris2/bits/errno.h: Likewise.
	* sysdeps/i386/dl-machine.c (elf_machine_rel) [RTLD_BOOTSTRAP]: Don't
	use GL(dl_rtld_map), use map parameter.
	* sysdeps/sh/dl-machine.h (elf_machine_rela): Likewise.
	* sysdeps/unix/sysv/linux/i386/sysdep.S: Define errno in .tbss if
	USE_TLS && HAVE___THREAD.
	* sysdeps/unix/sysv/linux/i386/sysdep.h: Unify SETUP_PIC_REG
	definitions.  If USE_TLS && HAVE___THREAD store errooor value using
	TLS code sequence.
	* sysdeps/unix/sysv/linux/i386/i686/sysdep.h: Likewise.

	* sysdeps/unix/sysv/linux/getcwd.c: No real need to restore errno.
	* sysdeps/unix/sysv/linux/grantpt.c: Likewise.
	* sysdeps/unix/sysv/linux/internal_statvfs.c: Likewise.
	* sysdeps/unix/sysv/linux/msgctl.c: Likewise.
	* sysdeps/unix/sysv/linux/readv.c: Likewise.
	* sysdeps/unix/sysv/linux/writev.c: Likewise.
