When I saw this, I thought "/etc/nsswitch.conf"... I was unaware that
there had been a different file performing this function in the past.
Apparently glibc's gethostbyname() switched to using /etc/nsswitch.conf in
place of the /etc/host.conf used by libc5's implementation of
gethostbyname().

So much history... I must have slept too much in class... :)
