+ * hesiod/hesiod_p.h (struct hesiod_p): Add classes array.
+ * hesiod/hesiod.c (hesiod_init): Initialize classes. Fail if no
+ valid classes were given or if both are equal.
+ (hesiod_resolve): Use ctx->classes instead of hardcoded C_IN
+ and C_HS order.
+ (parse_config_file): Handle classes keyword.
+ * hesiod/README.hesiod: Mention addition of the classes keyword.

* configure.in: Add test for availability of libaudit.
