8.4.1 compile error on Linux slackware

[none]

I have always been able to get bind 8.x.x to compile on this server, but am
getting an error now with 8.4.1


gcc -D_GNU_SOURCE -I../../port/linux/include -I../../include  -g  -c
ns_main.c
ns_main.c: In function `setupifp':
ns_main.c:2328: structure has no member named `ifa_dstaddr'
ns_main.c:2328: structure has no member named `ifa_dstaddr'
make[2]: *** [ns_main.o] Error 1
make[2]: Leaving directory `/usr/src/bin/named'
make[1]: *** [all] Error 1
make[1]: Leaving directory `/usr/src/bin'
make: *** [all] Error 1

Any suggestions?

Thanks
Dave
