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