These values are defined in nameser.h, and conditionalized on constants in hns_config.h.

Edit hns_config.h so that these constants are not defined:

/* Define to 1 if you have the <arpa/nameser_compat.h> header file. */
//#define HAVE_ARPA_NAMESER_COMPAT_H 1

/* Define to 1 if you have the <arpa/nameser.h> header file. */
//#define HAVE_ARPA_NAMESER_H 1

The code now compiles OK.

But arpa/nameser.h and arpa/nameser_compat.h exists:

$ ls /usr/include/arpa
ftp.h  inet.h  nameser_compat.h  nameser.h  telnet.h  tftp.h

The T_ types used in htdig.c are not defined in them, though.

Same compiler errors on Slackware 14.2, but I do have those defined enabled

/* Define to 1 if you have the <arpa/nameser_compat.h> header file. */
#define HAVE_ARPA_NAMESER_COMPAT_H 1

/* Define to 1 if you have the <arpa/nameser.h> header file. */
#define HAVE_ARPA_NAMESER_H 1

It may be that whatever libs I have are too old, Slackware can be like that

T_DNSKEY is defined, but not in arpa/nameser.h, so I'll need to do some more digging

As they are data types it can't handle, I'm just going to remove them for now
