Update.
2000-01-03 Andreas Jaeger <aj@suse.de> * include/resolv.h: Remove declarations for __ns_name_ntop and __ns_name_unpack since those are available in resolv/arpa/nameser.h. 2000-01-03 Andreas Jaeger <aj@suse.de> * time/tst-strptime.c (test_tm): Add tests for all fields of struct tm. 2000-01-03 Ulrich Drepper <drepper@cygnus.com> * string/bits/string2.h (__strsep_g): Don't handle empty __S special. 2000-01-03 Andreas Jaeger <aj@suse.de> * string/tester.c (test_strsep): Add one more test. 2000-01-03 Philip Blundell <philb@gnu.org> * string/tester.c (test_mempcpy): New function. (main): Call it. (test_memcpy): Test unaligned cases too. * sysdeps/arm/bits/string.h (_HAVE_STRING_ARCH_mempcpy): Define. * sysdeps/arm/fpu/bits/mathdef.h: New file. * nss/Makefile: Add rules to build makedb.
