  dnl Prerequisites of lib/canon-host.c.

  AC_CHECK_HEADERS(netdb.h sys/socket.h netinet/in.h arpa/inet.h)

  dnl Add any libraries as early as possible.
  dnl In particular, inet_ntoa needs -lnsl at least on Solaris 2.5.1,
  dnl so we have to add -lnsl to LIBS before checking for that function.
  AC_SEARCH_LIBS(gethostbyname, [inet nsl])

  dnl These come from -lnsl on Solaris 2.5.1.
