Update.

2002-04-03  Ulrich Drepper  <drepper@redhat.com>

	* locale/programs/charmap.c (charmap_read): If the charmap doesn't
	define a code_set_name provide one based on the filename.

	* malloc/hooks.c: Define weak_variable correctly for _LIBC.

2001-12-28  Andreas Jaeger  <aj@suse.de>

	* time/mktime.c (__mktime_internal): Check for year < 70
	[PR libc/2738].

	* sysdeps/generic/w_lgamma.c: Initialized local_signgam.
	* sysdeps/generic/w_lgammaf.c: Likewise.
	* sysdeps/generic/w_lgammal.c: Likewise [PR libc/2854].

	* debug/catchsegv.sh (exval): Quote [ in pattern [PR libc/2902].
	Adjust for new output format of the backtrace functions.

	* misc/syslog.c (vsyslog): Only use cleanup handler if
	_LIBC_REENTRANT is defined [PR libc/2924].

	* sysdeps/s390/s390-64/bits/byteswap.h: Likewise [PR libc/2757].
