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.
