+dnl At least on IRIX, cpp test for netinet/tcp.h will fail unless netinet/in.h
+dnl is included first.  So can't just use AC_CHECK_HEADERS; do it this way:
+AC_CHECK_HEADERS([netinet/in.h])
+AC_MSG_CHECKING([for netinet/tcp.h])
+AC_TRY_CPP([
+#ifdef HAVE_NETINET_IN_H
+#include <netinet/in.h>
+#endif
+#include <netinet/tcp.h>
+], [AC_DEFINE(HAVE_NETINET_TCP_H) AC_MSG_RESULT(yes)],
+[AC_MSG_RESULT(no)])
