[cups.development] Problem building 1.2.0 on Solaris 10/SPARC

[Albert Chin]

I'm running into the following build error with cups-1.2.0 on Solaris
20/SPARC:
  $ gtar jxf cups-1.2.0-source.tar.bz2
  $ cd cups-1.2.0
  $ ./configure
  $ gmake
  ...
  Compiling snmp.c...

<net/if.h> has:
  struct ifaddr {
          struct  sockaddr ifa_addr;      /* address of interface */
          union {
                  struct  sockaddr ifu_broadaddr;
                  struct  sockaddr ifu_dstaddr;
          } ifa_ifu;
  #define ifa_broadaddr   ifa_ifu.ifu_broadaddr   /* broadcast address */
  #define ifa_dstaddr     ifa_ifu.ifu_dstaddr     /* other end of p-to-p link */
          struct  ifnet *ifa_ifp;         /* back-pointer to interface */
          struct  ifaddr *ifa_next;       /* next address for interface */
  };

If a platform does not have getifaddrs(), a custom struct in
cups/http-private.h is used. However, this custom struct does not
define a ifa_broadaddr member.

Shouldn't the custom ifaddrs struct in cups/http-private.h have:
  union { 
    struct  sockaddr *ifu_broadaddr;
    struct  sockaddr *ifu_dstaddr;
  } ifa_ifu;
