Update.
1999-12-03 Andreas Jaeger <aj@suse.de> * nss/getXXbyYY.c: Include <resolv.h> (FUNCTION_NAME): Use res_ninit instead of res_init. * nss/getXXbyYY_r.c [NEED__RES]: Include <resolv.h> for _res declaration and prototypes. Remove extra _res declaration. (INTERNAL): Use thread aware res_ninit function. * inet/gethstbyad_r.c: Include <resolv.h>. * resolv/res_data.c: Update from Bind 8.2.2-P5. Moved res_init to res_libc.c. Disabled unneeded functions. * resolv/res_libc.c: New file. * Versions.def: Add version GLIBC_2.2 for libpthread. Add versions GLIBC_2.1 and GLIBC_2.2 for libresolv. * include/resolv.h: Add internal interfaces. * resolv/Makefile (routines): Add new files. (libresolv-routines): Likewise. (distribute): Likewise. * resolv/gethnamaddr.c: Use thread safe resolver functions. * resolv/nss_dns/dns-host.c: Likewise. * resolv/nss_dns/dns-network.c: Likewise. * resolv/arpa/nameser.h: Update from Bind 8.2.2-P5. * resolv/nsap_addr.c: Likewise. * resolv/res_comp.c: Likewise. * resolv/res_debug.c: Likewise. * resolv/res_init.c: Likewise. * resolv/res_mkquery.c: Likewise. * resolv/res_query.c: Likewise. * resolv/res_send.c: Likewise. * resolv/resolv.h: Likewise. * resolv/Versions: Add __res_state and __res_ninit with version GLIBC_2.2 to libc. Add new interfaces with version GLIBC_2.2 to libresolv. * resolv/Banner: Update. * include/arpa/nameser_compat.h: New file. * resolv/ns_name.c: New file from Bind 8.2.2-P5. * resolv/ns_netint.c: Likewise. * resolv/ns_parse.c: Likewise. * resolv/ns_print.c: Likewise. * resolv/ns_samedomain.c: Likewise. * resolv/ns_ttl.c: Likewise. * resolv/arpa/nameser_compat.h: Likewise. * resolv/res_debug.h: Likewise. Some patches are based on work done by Adam D. Bradley <artdodge@cs.bu.edu>. * sysdeps/unix/sysv/linux/configure.in: Remove check for ldconfig, set always use_ldconfig instead.
