2001-01-02 Ulrich Drepper <drepper@redhat.com>
+ * 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>
+
* intl/dcigettext.c (guess_category_value): Rewrite so that LANGUAGE
value is ignored if the selected locale is the C locale.
* intl/tst-gettext.c: Set locale for above change.
