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>.
