Update.

2003-01-11  Jim Meyering  <jim@meyering.net>

	* io/ftw.c [HAVE_CONFIG_H]: Include <config.h>.

	the basename, not the entire file name.

2003-01-12  Ulrich Drepper  <drepper@redhat.com>

	* string/tester.c (test_strcpy): Disable last added strcpy until
	it is fixed.

2003-01-11  Philip Blundell  <philb@gnu.org>

	* Makerules: Add vpath for %.dynsym and %.so so that the
	implicit rule chaining for check-abi works.

2003-01-11  Kaz Kojima  <kkojima@rr.iij4u.or.jp>

	* sysdeps/unix/sysv/linux/sh/sysdep.h (SYSCALL_ERROR_HANDLER):
	Add non-PIC case.

2003-01-11  Jakub Jelinek  <jakub@redhat.com>

	* elf/tls-macros.h [__ia64__] (__TLS_CALL_CLOBBERS): Define.
	[__ia64__] (TLS_LE, TLS_IE): Fix typos.  Add ;; at start of asm if
	gp is used early.
	[__ia64__] (TLS_LD, TLS_GD): Likewise.  Use __TLS_CALL_CLOBBERS.
	* elf/Makefile ($(objpfx)tst-tlsmod5.so, $(objpfx)tst-tlsmod6.so):
	Ensure libc.so in DT_NEEDED.
	* sysdeps/alpha/dl-machine.h (elf_machine_rela): Move
	CHECK_STATIC_TLS before l_tls_offset use.
	* sysdeps/i386/dl-machine.h (elf_machine_rel, elf_machine_rela):
	Likewise.

	Allocate TLS_PRE_TCB_SIZE bytes below result.
	(_dl_deallocate_tls) [TLS_DTV_AT_TP]: Adjust before freeing.
	* sysdeps/generic/libc-tls.c (__libc_setup_tls): If
	TLS_INIT_TP_EXPENSIVE is not defined, allocate even if no PT_TLS
	segment has been found.  If TLS_DTV_AT_TP, allocate TLS_PRE_TCB_SIZE
	bytes below result and add tcb_offset to memsz.
	* sysdeps/ia64/dl-tls.h (__tls_get_addr): New prototype.
	* sysdeps/ia64/dl-machine.h: Include tls.h.
	(elf_machine_type_class): Return ELF_RTYPE_CLASS_PLT for TLS relocs
	too.
	(elf_machine_rela): Assume if sym_map != NULL sym is non-NULL too.
	Handle R_IA64_DTPMOD*, R_IA64_DTPREL* and R_IA64_TPREL* relocations.
	* sysdeps/ia64/libc-tls.c: New file.

	ftruncate64, pread64, pwrite64, truncate64 entries.
	* sysdeps/unix/sysv/linux/powerpc/powerpc64/sysdep.h

2003-01-12  Ulrich Drepper  <drepper@redhat.com>

	* elf/dl-close.c (_dl_close): Add several asserts.  Correct and
	simplify test for unloading.  If loader of a DSO is unloaded do not
	use its scope anymore.  Fall back to own scope and adjust opencounts.
	Fix several comments.
	* elf/dl-deps.c (_dl_map_object_deps): Always allocate memory for
	the l_searchlist, not only for l_initfini.

	* elf/dl-lookup.c (add_dependencies): Avoid creating relocation
	dependencies if objects cannot be removed.  Remove object with the
	definition as not unloadable if necessary.

	* elf/reldep6.c: Create relocation dependency before closing the first
	module.
