Update.
2001-01-14 Jakub Jelinek <jakub@redhat.com> * nss/getent.c (print_aliases, aliases_keys, ethers_keys, netgroup_keys, print_rpc, rpc_keys, print_shadow, shadow_keys): New functions. (group_keys, hosts_keys, network_keys, passwd_keys, protocols_keys): If number is 0, list all. (services_keys): Likewise. Lookup aliases as well. (databases): New table. (build_doc): Prepare argp doc text with list of supported databases. (main): Change to table driven processing. 2001-01-14 Thorsten Kukuk <kukuk@suse.de> * sunrpc/xdr.c (xdr_long, xdr_u_long): Fix comments about this functions. 2001-01-03 Jakub Jelinek <jakub@redhat.com> * sunrpc/xdr.c (xdr_long, xdr_u_long): Return FALSE if trying to encode value which does not fit in the 32bit type.
