From f03fc94e7df1078959a4fa4a4b5c4e02b09a2bc1 Mon Sep 17 00:00:00 2001
From: Peter Eisentraut <peter_e@gmx.net>
Date: Mon, 28 Aug 2000 11:53:23 +0000
Subject: [PATCH] New configure test for flex, which recognizes only flex but
 does so in all incarnations (I hope). When an acceptable flex version is not
 found, print instructive error messages from both configure and the
 makefiles, so that users can continue building anyway.
