From 1c8244ec678dc4c2dffdcffd5cb51c04e9fc5dfc Mon Sep 17 00:00:00 2001
From: Tom Lane <tgl@sss.pgh.pa.us>
Date: Tue, 23 May 2000 04:55:44 +0000
Subject: [PATCH] Twiddle C++ configuration checks so that we #include <string>
 (if it exists) before testing 'using namespace std'.  This is necessary on
 some C++ setups where the compiler won't take a 'using' until you've included
 a header that mentions namespace std.  (Pretty braindead if you ask me,
 but...)
