Update.

	* manual/Makefile (TEXI2PDF): Change to texi2dvi --pdf.
	Suggested by Minko Markov <mmarkov@home.com>.

2001-01-02  Franz Sirl  <Franz.Sirl-kernel@lauterbach.com>

	* sysdeps/powerpc/elf/start.S (__data_start): Make it global.
	* sysdeps/powerpc/dl-machine.c (dl_reloc_overflow): Print the name of
	the failing symbol.
	(__process_machine_rela): Pass symbol to dl_reloc_overflow().

2001-01-02  Ben Collins  <bcollins@debian.org>

	* time/tzset.c (tzset_internal): Make sure we fall back to UTC
	if TZ is not set and TZDEFAULT is not present.

2001-01-01  Ben Collins  <bcollins@debian.org>

	* string/strings.h: Make sure we declare our functions even if
	string.h is already included, based on whether or not __USE_BSD is
	defined.

2001-01-02  Ulrich Drepper  <drepper@redhat.com>

	* dlfcn/dlerror.c (dlerror): Handle call of dlerror() before any
	other dlopen() and dlsym().
	Based on a patch by Ben Collins <bcollins@debian.org>.

2001-01-02  Andreas Jaeger  <aj@suse.de>

	* dlfcn/errmsg1.c (main): Call dlerror initially.
	Reported by Ben Collins <bcollins@debian.org>.
