* sysdeps/ia64/elf/configure.in: Add TLS check.

	From Ian Wienand <ianw@cse.unsw.edu.au>.
	* sysdeps/ia64/elf/configure: Regenerated.

2002-11-07  Roland McGrath  <roland@redhat.com>

	* libio/fileops.c (_IO_new_file_overflow): Use INTUSE(_IO_do_write) in
	place of _IO_new_do_write.
	[_LIBC] (_IO_do_write): Define as macro for _IO_new_do_write and
	#undef before versioned_symbol use.

	* string/test-string.h (test_init): Fill BUF1 and BUF2 with nonzero
	characters.
