all those .c changes were mostly fixes of warnings for the change in rebuild.sh being changed to use -Wall.

gethostbyname was almost completely rewritten to work better with ipv6 for gopherd.sh
gopherd.sh was rewritten to use gethostbyname instead of dig and to cut out any link-local interface indicators from the output of hop0 and to ignore an error if ipA -> hostname -> ipB causes ipA to be not the same as ipB.
Don't remember if there's anything else.
