/usr/include/bits/string2.h warnings

[Frédéric L. W. Meunier <0 at pervalidus dot net>]

What causes the following warnings? IIRC, I got nothing with
2.1.3 from Slackware 7.1 and 2.0.7 from RedHat 5.2. The result
using 2.2 and up (they also appear building XFree86):

BTW, where's db-Makefile? Also note the double "question". From
the FAQ:

2.16.   How do I create the databases for NSS?

{AJ} If you have an entry "db" in /etc/nsswitch.conf you should also create
the database files.  The glibc sources contain a Makefile which does the
necessary conversion and calls to create those files.  The file is
`db-Makefile' in the subdirectory `nss' and you can call it with `make -f
db-Makefile'.  Please note that not all services are capable of using a
database.  Currently passwd, group, ethers, protocol, rpc, services shadow
and netgroup are implemented.  See also question question 2.31.
