In our configure.ac we have (note defines and -lxnet)

*-*-hpux*)
        # these lines are needed to fix a problem for HP-UX
        # HP-UX define two versions of sockets, one BSD and one X/Open
        # these versions are not binary compatible (BSD use int where X/Open
        # use socklen_t == size_t) and different libraries (BSD in libc and
        # X/Open in libxnet). X/Open is used if _XOPEN_SOURCE and
        # _XOPEN_SOURCE_EXTENDED are defined. To complicate the things gcc
        # by default define _XOPEN_SOURCE_EXTENDED so define always both
        # constants and link always libxnet!
        CPPFLAGS="$CPPFLAGS -D_XOPEN_SOURCE -D_XOPEN_SOURCE_EXTENDED"
        LIBS="$LIBS -lxnet"
        AC_SEARCH_LIBS(gethostbyname, nsl)
        if test "$enable_krb5" = "yes" ; then
                AC_SEARCH_LIBS(gss_init_sec_context, [gssapi_krb5 gssapi])
                if test "$ac_cv_search_gss_init_sec_context" != no; then
                        AC_DEFINE(ENABLE_KRB5, 1, [Defined if
--enable-krb5 used and library detected])
                fi
        fi

        AM_CONDITIONAL(MINGW32, false)
        ;;

But for some reason it doesn't work for Michael. Perhaps is he linking
with -lc too ??
