2000-01-07 Andreas Jaeger <aj@suse.de> Add support for Berkeley db 3.0.x and merge db support: * nss/nss_db/dummy-db.h (struct db30): New. (struct dbc30): New. Added DB30* flags. * nss/makedb.c: Move all database routines to db-open.c. (main): Adjust to interface changes. Load database early to initialize version dependend variables. * nss/db-open.c: Merge database routines from makedb.c. Define version dependend constansts as variables. (load_db): Check also for db 3. (internal_setent): Call dbopen. (db_cursor): New function from makedb; handles db 3 now. (dbopen): New function from makedb; handles db 3. * nss/nss_db/db-XXX.c: Use db_notfound since the value is different in different DB versions. * nss/nss_db/nss_db.h: Add version dependend constants as variables, add exportet interfaces from db-open.c. * nss/Makefile ($(objpfx)makedb): Link against db-open. 2000-01-07 Ulrich Drepper <drepper@cygnus.com> * misc/error.c: Don't use `defined _LIBC', only `_LIBC'. Reported by Jim Meyering. * time/strftime.c: Pretty printing. 2000-01-07 Andreas Jaeger <aj@suse.de> * manual/socket.texi (Host Names): Fix example. Reported by Marco Budde <budde@telos.de>.
