This header is a bit more generic now than it was in the version you've
modified. It is now used on GNU/Linux, and intends to serve other
packages than just freebsd-utils.

(hence the questions below, please answer if possible!).

This is an IPv4 address right? Any idea what is it used for? What's
special about packets sent to / received from this address?

Btw, what about the other groups not defined by Glibc? Should these be
added too?

#define INADDR_ALLRPTS_GROUP    (u_int32_t)0xe0000016   /* 224.0.0.22,
IGMPv3 */
#define INADDR_CARP_GROUP       (u_int32_t)0xe0000012   /* 224.0.0.18 */
#define INADDR_PFSYNC_GROUP     (u_int32_t)0xe00000f0   /* 224.0.0.240 */
#define INADDR_ALLMDNS_GROUP    (u_int32_t)0xe00000fb   /* 224.0.0.251 */

Thanks!
