Every file that uses libc_hidden_nolink_sunrpc or libnsl_hidden_nolink_def needs to include shlib-compat.h. Currently, most of them are getting it via stdio.h, because libio.h refers to SHLIB_COMPAT when _LIBC is defined, so it includes shlib-compat.h. My experimental patch to not install libio.h breaks that chain; stdio.h no longer pulls in libio.h even for internal users. Accordingly, this patch adds #include <shlib-compat.h> to many files in sunrpc/ and nis/. There are also a small number of really obvious fixups to includes that caught my eye while proofreading the patch - not including headers twice in a row, not worrying about portability to Ultrix anymore, sort of thing. * nis/nis_add.c, nis/nis_addmember.c, nis/nis_call.c * nis/nis_checkpoint.c, nis/nis_clone_dir.c, nis/nis_clone_obj.c * nis/nis_clone_res.c, nis/nis_creategroup.c, nis/nis_defaults.c * nis/nis_destroygroup.c, nis/nis_domain_of.c * nis/nis_domain_of_r.c, nis/nis_error.c, nis/nis_file.c * nis/nis_free.c, nis/nis_getservlist.c, nis/nis_ismember.c * nis/nis_local_names.c, nis/nis_lookup.c, nis/nis_mkdir.c * nis/nis_modify.c, nis/nis_ping.c, nis/nis_print.c * nis/nis_print_group_entry.c, nis/nis_remove.c * nis/nis_removemember.c, nis/nis_rmdir.c, nis/nis_server.c * nis/nis_subr.c, nis/nis_table.c, nis/nis_util.c * nis/nis_verifygroup.c, nis/nis_xdr.c, nis/yp_xdr.c * nis/ypclnt.c, nis/ypupdate_xdr.c, sunrpc/auth_des.c * sunrpc/auth_none.c, sunrpc/auth_unix.c, sunrpc/authdes_prot.c * sunrpc/authuxprot.c, sunrpc/clnt_gen.c, sunrpc/clnt_perr.c * sunrpc/clnt_raw.c, sunrpc/clnt_simp.c, sunrpc/clnt_tcp.c * sunrpc/clnt_udp.c, sunrpc/clnt_unix.c, sunrpc/des_crypt.c * sunrpc/des_soft.c, sunrpc/get_myaddr.c, sunrpc/key_call.c * sunrpc/key_prot.c, sunrpc/netname.c, sunrpc/pm_getmaps.c * sunrpc/pm_getport.c, sunrpc/pmap_clnt.c, sunrpc/pmap_prot.c * sunrpc/pmap_prot2.c, sunrpc/pmap_rmt.c, sunrpc/publickey.c * sunrpc/rpc_cmsg.c, sunrpc/rpc_dtable.c, sunrpc/rpc_prot.c * sunrpc/rpc_thread.c, sunrpc/rtime.c, sunrpc/svc.c * sunrpc/svc_auth.c, sunrpc/svc_raw.c, sunrpc/svc_run.c * sunrpc/svc_tcp.c, sunrpc/svc_udp.c, sunrpc/svc_unix.c * sunrpc/svcauth_des.c, sunrpc/xdr.c, sunrpc/xdr_array.c * sunrpc/xdr_float.c, sunrpc/xdr_intXX_t.c, sunrpc/xdr_mem.c * sunrpc/xdr_rec.c, sunrpc/xdr_ref.c, sunrpc/xdr_sizeof.c * sunrpc/xdr_stdio.c: Include shlib-compat.h. * sunrpc/des_crypt.c, sunrpc/des_soft.c: No need to include abi-versions.h as well as shlib-compat.h. * sunrpc/get_myaddr.c: Remove obsolete comment. * sunrpc/pmap_rmt.c: Remove obsolete comment and #undef. * sunrpc/rpc_thread.c: Include libc-lock.h only once. * resolv/res_libc.c: Include shlib-compat.h only once.
