From 1fd16ce13cec7eb0b4ddf4566c86a7830950a5d4 Mon Sep 17 00:00:00 2001
From: Vadim Zeitlin <vadim@wxwidgets.org>
Date: Wed, 15 Jan 2003 22:04:32 +0000
Subject: [PATCH] added checks to prevent running sub configure scripts
 directly (they can only be executed by the top level configure)

git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@18752 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
