Update.
2002-04-14 Jakub Jelinek <jakub@redhat.com> * elf/dl-lookup.c (_dl_lookup_symbol): Move add_dependency call to the end of the function. Pass original flags to recursive call if add_dependency failed. (_dl_lookup_versioned_symbol): Likewise. 2002-04-13 Jakub Jelinek <jakub@redhat.com> * time/mktime.c (__mktime_internal): If year is 69, don't bail out early, but check whether it overflowed afterwards. * time/tst-mktime.c (main): Add new tests. * debug/xtrace.sh: Fix program name in help message. Patch by Roger Luethi <rl@hellgate.ch>.
