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.
