From d30e2ac306c26271474e1b96c087ff8e6d859ac2 Mon Sep 17 00:00:00 2001
From: Tom Lane <tgl@sss.pgh.pa.us>
Date: Tue, 20 Apr 1999 00:26:32 +0000
Subject: [PATCH] Portability patches for HPUX 11 and Unixware in configure and
 related files.  Also remove float.c's gratuitous redeclaration of isinf() ...
 looks like there are more decls in there that ought to be in config.h, but
 I'll leave well enough alone for now ...
