Update.
1998-04-04 Andreas Jaeger <aj@arthur.rhein-neckar.de>
* resolv/Makefile: Include ../Makeconfig - needed for building
static NSS module.
1998-04-04 Andreas Jaeger <aj@arthur.rhein-neckar.de>
* hesiod/Makefile (libnss_hesiod-inhibit-o): Remove condition for
static-nss since we don't want hesiod in the static NSS.
* nss/Makefile: Build only nss_files as static.
* nss/function.def: Remove support for service db.
1998-04-04 09:44 H.J. Lu <hjl@gnu.org>
* Makeconfig (CPPFLAGS-.oS): Add -DPIC.
1998-04-04 18:29 Tim Waugh <tim@cyberelk.demon.co.uk>
* posix/wordexp-test.c: Make IFS per test-case.

NSS allows using +different services (e.g. NIS, files, db, hesiod) by just changing one +configuration file (/etc/nsswitch.conf) without relinking any +programs. The only disadvantage is that now static libraries need to +access shared libraries. This is handled transparently by the GNU C +library. + +A solution is to configure glibc with --enable-static-nss. In this +case you can create a static binary that will use only the services +dns and files (change /etc/nsswitch.conf for this). You need +to link explicitly against all these services.
