+[A22] {UD} The problem is that the IPv6 development still has not reached
+a point where it is stable.  There are still lots of incompatible changes

+[Q23]	``When compiling GNU libc I get lots of errors saying functions

+
+[A23] {EY} This is *exactly* the same problem that I was having.  The
+problem was due to the fact that the autoconfigure didn't correctly
+detect that linker flag --no-whole-archive was supported in my linker.
+In my case it was because I had run ./configure with bogus CFLAGS, and
+the test failed.
+
+One thing that is particularly annoying about this problem is that
+once this is misdetected, running configure again won't fix it unless
+you first delete config.cache.
+
+{UD} Starting with glibc-2.0.3 there should be a better test to avoid
+some problems of this kind.  The setting of CFLAGS is checked at the
+very beginning and if it is not usable `configure' will bark.

+
+[A24]	The glibc NIS+ implementation uses a /var/nis/NIS_COLD_START
+	file for storing information about the NIS+ server and their
+	public keys, because the nis.conf file do not contain all
+	necessary information.  You have to copy a NIS_COLD_START file
+	from a Solaris client (the NIS_COLD_START file is byte order
+	independend) or generate it new with nisinit from the nis-tools
+	(look at http://www-vt.uni-paderborn.de/~kukuk/linux/nisplus.html).
