+ * (<resolv.h>, <arpa/nameser.h>. However, res_update(), res_mkupdate(),
+ * and res_mkupdrec() are in the public libresolv interface in Solaris,
+ * so we can't easily remove them. Thus, ISC's new versions of res_mkupdate()
+ * etc. can't be exposed under their original names.
+ *
+ * res_nmkupdate() and res_nupdate are new. We could either change them
+ * to accept the <arpa/nameser.h> ns_updrec, or leave them unchanged and
+ * undocumented. Since ISC may change ns_updrec again, we pick the latter
+ * solution for now.
