From b6edc2873a0137d8129489ad412372489ea686bf Mon Sep 17 00:00:00 2001
From: Quincey Koziol <koziol@hdfgroup.org>
Date: Tue, 26 Apr 2011 16:41:41 -0500
Subject: [svn-r20651] Description: 	Switch from using 'pthread_create' to
 'pthread_self' when trying to detect the pthread library, so that the Intel C
 compiler is happier with the prototype.

Tested on:
	Linux/64 2.6 (koala) w/Intel C
	(h5committested on duty, jam & linew)
